+%\section{Introduction}
+%\label{sec:intro}
+%
+% The Association for Computing
+% Machinery\footnote{\url{http://www.acm.org/}} is the world's largest
+% educational and scientific computing society, which delivers
+% resources that advance computing as a science and a
+% profession. It was one of the
+% early adopters of \TeX\ for its typesetting.
+%
+% It provided several different classes for a number of journals and
+% conference proceedings. Unfortunately during the years since these
+% classes were written, the code was patched many times, and
+% supporting different versions of the classes became difficult.
+%
+% This package provides the uniform interface for all ACM
+% publications. It is intended to replace all the different classes and
+% packages and provide an up-to-date \LaTeX\ package.
+%
+% This package uses only free \TeX\ packages and fonts included in \TeX
+% Live, Mik\TeX\ and other popular \TeX\ distributions. It is
+% intended to be published in these distributions itself, which
+% minimizes users' efforts in the installation and support of this
+% package.
+%
+% I am grateful to

+% commands and options can be safely left with their default values
+% or the values recommended by your conference or journal editors. If
+% you have problems or questions, do not hesitate to ask me directly
+% or the community at \url{https://github.com/borisveytsman/acmart},
+% \url{https://tex.stackexchange.com} or the closest \TeX\ Users
+% Group. The world-wide \TeX\ Users Group is at
+% \url{https://tug.org/}; please consider joining us if you use \TeX\
+% regularly.

+%\subsection{Installation}
+%\label{sec:ug_install}
+%
+% Most probably, you already have this package installed in your
+% favorite \TeX\ distribution; if not, you may want to upgrade. You
+% may need to upgrade it anyway since this package uses a number of
+% relatively recent packages, especially the ones related to fonts.
+%
+% The latest released version of this package can be found on CTAN:
+% \url{https://www.ctan.org/pkg/acmart}. The development version can
+% be found on GitHub: \url{https://github.com/borisveytsman/acmart}.
+% At this address you can file a bug report---or even contribute your
+% own enhancement by making a pull request.
+%
+% Please note that the version on Github is a development (or
+% experimental) version: please download it for testing new features.
+% The production version is the one on CTAN and ACM sites.
+%
+% Most users should not attempt to install this package themselves
+% but should rather rely on their \TeX\ distributions to provide it. If you
+% decide to install the package yourself, follow the standard rules:
+% \begin{enumerate}
+% \item Run |latex acmart.ins|. This will produce the file
+% |acmart.cls|
+% \item Put the files |acmart.cls| and |ACM-Reference-Format.bst|
+% in places where \LaTeX{} can find them (see \cite{TeXFAQ} or
+% the documentation for your \TeX{} system).\label{item:install}
+% \item Update the database of file names. Again, see \cite{TeXFAQ}
+% or the documentation for your \TeX{} system for the system-specific
+% details.\label{item:update}
+% \item The file |acmart.pdf| provides the documentation for the
+% package. (This is probably the file you are reading now.)
+% \end{enumerate}
+% As an alternative to items~\ref{item:install} and~\ref{item:update}
+% you can just put the files in the working directory where your
+% |.tex| file is.
+%
+%
+% This class uses a number of other packages. They are included in all
+% major \TeX\ distributions (\TeX Live, Mac\TeX, Mik\TeX) of 2015 and
+% later, so you probably have them installed. Just in case here is

+%\subsection{Invocation and options}
+%\label{sec:invocation}
+%
+% To use this class, put in the preamble of your document
+% \begin{quote}
+% \cs{documentclass}\oarg{options}|{acmart}|
+% \end{quote}
+% There are several options corresponding to the type of the document and
+% its general appearance. They are described below. Generally
+% speaking, the options have |key=value| forms, for example,
+% \begin{verbatim}
+% \documentclass[format=acmsmall, screen=true, review=false]{acmart}
+% \end{verbatim}
+%
+%
+% The option |format| describes the format of the output. There are
+% several possible values for this option, for example,
+% \begin{verbatim}
+% \documentclass[format=acmtog]{acmart}
+% \end{verbatim}
+% Actually the words |format=| can be omitted, e.g.,
+% \begin{verbatim}
+% \documentclass[acmtog, review=false]{acmart}
+% \end{verbatim}
+% The possible formats are listed in
+% Table~\ref{tab:opts_format}. Note that formats starting with |acm|
+% are intended for journals and transactions, while formats starting
+% with |sig| are intended for proceedings published as books.
+%
+% Note that sometimes conference proceedings are published as a
+% special issue (or issues) of an ACM journal. In this case, you
+% should use the journal format for a conference paper. Please
+% contact your conference committee if in doubt.
+%
+% \begin{table}
+% \centering
+% \caption{The possible values for the \texttt{format} option}
+% \label{tab:opts_format}
+% \begin{tabularx}{\textwidth}{>{\ttfamily}lX}
+% \toprule
+% \normalfont Value & Meaning\\
+% \midrule
+% manuscript & A manuscript. This is the default. \\
+% acmsmall & Small single-column format. Used for CIE, CSUR,
+% JACM, JDIQ, JEA, JERIC,
+% JETC, PACMCGIT, PACMHCI, PACMPL, TAAS, TACCESS, TACO,
+% TALG, TALLIP (formerly TALIP), TCPS, TDS,
+% TEAC, TECS, TELO, THRI, TIIS, TIOT, TISSEC, TIST, TKDD, TMIS,
+% TOCE, TOCHI, TOCL,
+% TOCS, TOCT, TODAES, TODS, TOIS, TOIT, TOMACS, TOMM (formerly
+% TOMCCAP), TOMPECS, TOMS, TOPC, TOPLAS, TOPS,
+% TOS, TOSEM, TOSN, TQC, TRETS,
+% TSAS, TSC, TSLP and TWEB, including special issues. \\
+% acmlarge & Large single-column format. Used for DTRAP, HEALTH,
+% IMWUT, JOCCH, POMACS and TAP, including special issues. \\
+% acmtog & Large double-column format. Used for
+% TOG, including annual conference Technical Papers.\\
+% sigconf & Proceedings format for most ACM
+% conferences (with the exceptions listed below) and all ICPS
+% volumes.\\
+% sigplan & Proceedings format for SIGPLAN conferences.\\
+% \bottomrule
+% \end{tabularx}
+% \end{table}
+%
+% Starting in 2020, ACM retired formats |sigchi| and |sigchi-a|.
+% SIGCHI conferences now use |sigconf| format for their publications.
+% If a file uses |sigchi| format, a warning is issued, and the format
+% is automatically switched to |sigconf|. Format |sigchi-a| can be
+% used for non-ACM documents only (see Section~\ref{sec:sigchi-a}).
+%
+% There are several Boolean options that can take |true| or |false|
+% values. They are listed in Table~\ref{tab:opts_bool}. The words
+% |=true| can be omitted when setting a Boolean option, so instead of
+% |screen=true| one can write just |screen|, for example,
+% \begin{verbatim}
+% \documentclass[acmsmall, screen, review]{acmart}
+% \end{verbatim}
+% The option |review| is useful when combined with the |manuscript| format
+% option. It provides a version suitable for reviewers and
+% copy editors.
+%
+% Two samples in the |samples| directory, |manuscript| and
+% |acmsmall-submission|, show manuscripts formatted for submission to
+% ACM.
+%
+% The default for the option |screen| depends on the publication. At
+% present it is |false| for all publications \emph{but} PACM, since
+% PACM is now electronic-only. Thus PACM titles~(see
+% Table~\ref{tab:pubs}) set this option to |true|. In the future this
+% option may involve additional features suitable for on-screen
+% versions of articles.
+%
+% The option |natbib| is used when the corresponding
+% \BibTeX\ style is based on |natbib|. In most cases you do not need
+% to set it. See
+% Section~\ref{sec:ug_bibliography}.
+%
+% The option |anonymous| is used
+% for anonymous review processes and causes all author information to be
+% obscured.
+%
+% The option |timestamp| is used to include a time stamp in the
+% footer of each page. When preparing a document, this can help avoid
+% confusing different revisions. The footer also includes the page range of
+% the document. This helps detect missing pages in hard copies.
+%
+% The option |authordraft| is intended for author's drafts that are not
+% intended for distribution. It typesets a copyright block to give the
+% author an idea of its size and the overall size of the paper but
+% overprints it with the phrase ``Unpublished working draft. Not for
+% distribution.'', which is also used as a watermark. This option sets
+% |timestamp| and |review| to |true|, but these can be
+% overriden by setting these options to |false| \emph{after}
+% setting |authordraft| to |true|.
+%
+% The option |balance| determines whether the last page in the two
+% column mode has balanced columns. By default it is |true|; however,
+% it may lead to problems for some documents. Set it to |false| if
+% you encounter compilation errors. Note that for one page documents
+% \cs{balance} command might cause problems.
+%
+% The option |urlbreakonhyphens| determines whether URLs can be split
+% between lines after hyphens. By default it is true. Set it to
+% |false| to disallow these breaks.
+%

+%
+%\subsection{Top matter}
+%\label{sec:ug_topmatter}
+%
+% A number of commands set up \emph{top matter} or (in
+% computer science jargon) \emph{metadata} for an article. They
+% establish the publication name, article title, authors, DOI and
+% other data. Some of these commands, like \cs{title} and \cs{author},
+% should be put by the authors. Others, like \cs{acmVolume} and
+% \cs{acmDOI}---by the editors. Below we describe these commands and
+% mention who should issue them. These macros should be used
+% \emph{before} the \cs{maketitle} command. Note that in previous
+% versions of ACM classes some of these commands should be used before
+% \cs{maketitle}, and some after it. Now they all must be used before
+% \cs{maketitle}.
+%
+%
+% This class internally loads the |amsart| class, so many top-matter
+% commands are inherited from |amsart|~\cite{Downes04:amsart}.
+%
+% \DescribeMacro{\acmJournal}%
+% The macro \cs{acmJournal}\marg{shortName} sets the name of the
+% journal or transaction for journals and transactions. The argument
+% is the short name of the publication \emph{in uppercase}, for
+% example,
+% \begin{verbatim}
+% \acmJournal{TOMS}
+% \end{verbatim}
+% The currently recognized journals are listed in
+% Table~\ref{tab:pubs}. Note that conference proceedings published in
+% \emph{book} form do not set this macro.
+%
+%
+%
+% \DescribeMacro{\acmConference}%
+% The macro
+% \cs{acmConference}\oarg{short name}\marg{name}\marg{date}\marg{venue} is
+% used for conference proceedings published in the book form. The
+% arguments are the following:
+% \begin{description}
+% \item[short name:] the abbreviated name of the conference (optional).
+% \item[name:] the name of the conference.
+% \item[date:] the date(s) of the conference.
+% \item[venue:] the place of the conference.
+% \end{description}
+% Examples:
+% \begin{verbatim}
+% \acmConference[TD'15]{Technical Data Conference}{November
+% 12--16}{Dallas, TX, USA}
+% \acmConference{SA'15 Art Papers}{November 02--06, 2015}{Kobe, Japan}
+% \end{verbatim}
+%
+% \DescribeMacro{\acmBooktitle}%
+% By default we assume that conference proceedings are published
+% in the book named \emph{Proceedings of \textsc{CONFERENCE}}, where
+% \textsc{CONFERENCE} is the name of the conference inferred from the
+% command \cs{acmConference} above. However, sometimes the book title
+% is different. The command \cs{acmBooktitle} can be used to set this
+% title, for example,
+% \begin{verbatim}
+% \acmBooktitle{Companion to the first International Conference on the
+% Art, Science and Engineering of Programming (Programming '17)}
+% \end{verbatim}
+%
+% An ACM paper should have either \cs{acmJournal} or
+% \cs{acmConference} command. If it has both (or more) commands, the
+% last one takes precedence. Note that if you have the command
+% \cs{acmConference} in a journal format like |acmsmall|, the class
+% will use conference format for bibstrip and reference citation
+% formatting. In the samples directory there is a file
+% |sample-acmsmall-conf.tex| with the example of this usage.
+%
+%
+%
+% \DescribeMacro{\editor}%
+% In most cases, conference proceedings are edited. You can use the
+% command \cs{editor}\marg{editor} to set the editor of the volume.
+% This command can be repeated, for example,
+% \begin{verbatim}
+% \editor{Jennifer B. Sartor}
+% \editor{Theo D'Hondt}
+% \editor{Wolfgang De Meuter}
+% \end{verbatim}
+%
+%
+% \DescribeMacro{\title}%
+% The command |\title|, as in the |amsart| class, has two arguments: one
+% optional, and one mandatory:
+% \begin{flushleft}
+% |\title[|\meta{ShortTitle}|]{|\meta{FullTitle}|}|
+% \end{flushleft}
+% The mandatory argument is the full title of the article. The
+% optional argument, if present, defines the shorter version of the
+% title for running heads. If the optional argument is absent, the
+% full title is used instead.
+%
+% It is expected that this command is inserted by the author of the
+% manuscript.
+%
+% \DescribeMacro{\subtitle}%
+% Besides title, ACM classes allow a subtitle, set with the
+% \cs{subtitle}\marg{subtitle} macro.
+%
+% The commands for specifying authors are highly structured.
+% The reason is they serve double duty: the authors' information is
+% typeset in the manuscript \emph{and} is used by the metadata
+% extraction tools for indexing and cataloguing. Therefore it is very
+% important to follow the guidelines exactly.
+%
+% \DescribeMacro{\author}%
+% \DescribeMacro{\orcid}
+% \DescribeMacro{\affiliation}%
+% \DescribeMacro{\email}%
+% The basic commands are \cs{author}, \cs{orcid} (for the researchers
+% registered with ORCID, \url{http://www.orcid.org/}), \cs{affiliation} and
+% \cs{email}. In the simplest case, you enter them in this order:
+% \begin{verbatim}
+% \author{...}
+% \orcid{...}
+% \affiliation{...}
+% \email{...}
+% \end{verbatim}
+% Do \emph{not} use the \LaTeX\ \cs{and} macro or commas, or \verb|\\|
+% between the authors! Each author deserves his or
+% her own \cs{author} command. An attempt to list several authors or
+% their e-mails in one command leads to a warning or an error. This
+% is not a bug, but the expected behavior.
+%
+% Note that some formats do not typeset e-mails or ORCID identifiers.
+% Do not worry: the metadata tools will get them.
+%
+% Sometimes an author has several affiliations. In this case, the
+% \cs{affiliation} command should be repeated:
+% \begin{verbatim}
+% \author{...}
+% \orcid{...}
+% \affiliation{...}
+% \affiliation{...}
+% \email{...}
+% \end{verbatim}
+% Similarly you can repeat the \cs{email} command.
+%
+% You may have several authors with the same affiliation, different
+% affiliations, or overlapping affiliations (author~$A_1$ is affiliated
+% with institutions $I_1$ and $I_2$, while author $A_2$ is affiliated
+% with $I_2$ only, author $A_3$ is affiliated with
+% $I_1$ and $I_3$, etc.). The recommended solution is to put the
+% \cs{affiliation} commands after each author, possibly repeating them:
+% \begin{verbatim}
+% \author{...}
+% \orcid{...}
+% \affiliation{...}
+% \affiliation{...}
+% \email{...}
+% \author{...}
+% \orcid{...}
+% \affiliation{...}
+% \email{...}
+% \author{...}
+% \orcid{...}
+% \affiliation{...}
+% \affiliation{...}
+% \email{...}
+% \end{verbatim}
+% In some cases, when several authors share the same affiliation, you can
+% try to save space using the format
+% \begin{verbatim}
+% \author{...}
+% \email{...}
+% \author{...}
+% \email{...}
+% \affiliation{...}
+% \end{verbatim}
+% However, this format is not generally recommended.
+%
+% \DescribeMacro{\additionalaffiliation}%
+% In some cases, too many affiliations can take too much space. The
+% command \cs{additionalaffiliation}\marg{affiliation} creates a
+% footnote after an author's name with the words ``Also with
+% \marg{affiliation}''. You should use this command only as a last
+% resort. An example of usage is:
+% \begin{verbatim}
+% \author{G. Tobin}
+% \author{Ben Trovato}
+% \additionalaffiliation{%
+% \institution{The Th{\o}rv{\"a}ld Group}
+% \streetaddress{1 Th{\o}rv{\"a}ld Circle}
+% \city{Hekla}
+% \country{Iceland}}
+% \affiliation{%
+% \institution{Institute for Clarity in Documentation}
+% \streetaddress{P.O. Box 1212}
+% \city{Dublin}
+% \state{Ohio}
+% \postcode{43017-6221}}
+% \end{verbatim}
+% Here Trovato and Tobin share their affiliation with the Institute
+% for Clarity in Documentation, but only Ben Trovato is affiliated
+% with The Th{\o}rv{\"a}ld Group.
+%
+%
+% \DescribeMacro{\position}%
+% \DescribeMacro{\institution}%
+% \DescribeMacro{\department}%
+% \DescribeMacro{\streetaddress}%
+% \DescribeMacro{\city}%
+% \DescribeMacro{\state}%
+% \DescribeMacro{\postcode}%
+% \DescribeMacro{\country}%
+% The \cs{affiliation} and \cs{additionalaffiliation} commands are
+% further structured to interact with the metadata extraction tools.
+% Inside these commands you should use the \cs{position},
+% \cs{institution}, \cs{department}, \cs{city}, \cs{streetaddress},
+% \cs{state}, \cs{postcode} and \cs{country} macros to indicate the
+% corresponding parts of the affiliation. Note that in some cases
+% (for example, journals) these parts are not printed in the resulting
+% copy, but they \emph{are} necessary since they are used by the XML
+% metadata extraction programs. Do \emph{not} put commas or |\\|
+% between the elements of \cs{affiliation}. They will be provided
+% automatically.
+%
+% The fields \cs{institution}, \cs{city} and \cs{country} are
+% mandatory. If they are not provided, an error or a warning is
+% issued. Currently the absence of \cs{country} produces and error;
+% ACM may change this in the future.
+%
+%
+% An example of the author block:
+% \begin{verbatim}
+% \author{A. U. Thor}
+% \orcid{1234-4564-1234-4565}
+% \affiliation{%
+% \institution{University of New South Wales}
+% \department{School of Biomedical Engineering}
+% \streetaddress{Samuels Building (F25), Kensington Campus}
+% \city{Sidney}
+% \state{NSW}
+% \postcode{2052}
+% \country{Australia}}
+% \email{author@nsw.au.edu}
+% \author{A. N. Other}
+% \affiliation{%
+% \institution{University of New South Wales}
+% \city{Sidney}
+% \state{NSW}
+% \country{Australia}}
+% \author{C. O. Respondent}
+% \orcid{1234-4565-4564-1234}
+% \affiliation{%
+% \institution{University of Pennsylvania}
+% \city{Philadelphia}
+% \state{PA}
+% \country{USA}}
+% \affiliation{%
+% \institution{University of New South Wales}
+% \city{Sidney}
+% \state{NSW}
+% \country{Australia}}
+% \end{verbatim}
+%
+% Note that the old ACM conference formats did not allow more than six
+% authors and required some effort from authors to achieve
+% alignment. The new format is much better in this.
+%
+% Sometimes an author works in several departments within the same
+% insitution. There could be two situations: the departments are
+% independent, or one department is within another. In the first
+% case, just repeat the command \cs{department} several times. To
+% handle the second case the command has an optional numerical
+% parameter. The departments with higher numbers are higher in the
+% organizational chart. Compare
+% \begin{verbatim}
+% \affiliation{%
+% \department[0]{Department of Lunar Studies} % 0 is the default
+% \department[1]{John Doe Institute} % higher than 0
+% \institution{University of San Serriffe}
+% \country{San Serriffe}}
+% \end{verbatim}
+% and
+% \begin{verbatim}
+% \affiliation{%
+% \department{Department of Lunar Studies} % Not in the John Doe Institute!
+% \department{John Doe Institute}
+% \institution{University of San Serriffe}
+% \country{San Serriffe}}
+% \end{verbatim}
+%
+%
+% The command \cs{affiliation} formats its output according to
+% American conventions. This might be wrong for some cases.
+% Consider, for example, a German address. In Germany, the postcode is
+% put before the city and is not separated by a comma. We can handle this
+% order using
+% \begin{verbatim}
+% \affiliation{%
+% \institution{Fluginstitut}
+% \streetaddress{Sonnenallee 17}
+% \postcode{123456}
+% \city{Helm}
+% \country{Germany}}
+% \end{verbatim}
+% However, the comma after the postcode is unfortunate: the address will
+% be typeset (in some formats) as
+% \begin{verbatim}
+% Fluginstitut
+% Sonenallee 17
+% 123456, Helm, Germany
+% \end{verbatim}
+%
+%
+% To overcome this problem, the command \cs{affiliation} has an
+% optional parameter |obeypunctuation|, which can be |false| (the
+% default) or |true|. If this parameter is |true|, \cs{afffiliation}
+% obeys the author's command. Thus
+% \begin{verbatim}
+% \affiliation[obeypunctuation=true]{%
+% \institution{Fluginstitut}\\
+% \streetaddress{Sonnenallee 17}\\
+% \postcode{123456}
+% \city{Helm},
+% \country{Germany}}
+% \end{verbatim}
+% will be typeset as
+% \begin{verbatim}
+% Fluginstitut
+% Sonenallee 17
+% 123456 Helm, Germany
+% \end{verbatim}
+%
+% Note that you should \emph{not} use this option for journals.
+%
+% It is expected that these commands are inserted by the author of the
+% manuscript.
+%
+% \DescribeMacro{\thanks}%
+% Like |amsart| (and unlike standard \LaTeX{}), we allow
+% |\thanks| only \emph{outside} of the commands |\title| and |\author|.
+% This command is obsolete and should \emph{not} be used in most
+% cases. Do not list your acknowledgments or grant sponsors here.
+% Put this information in the |acks| environment (see
+% Section~\ref{sec:ug_acks}).
+%
+% \DescribeMacro{\authorsaddresses}%
+% In some formats, addresses are printed as a footnote on the first
+% page. By default \LaTeX\ typesets them itself using the information
+% you give it. However, you can override its choice using the
+% commmand \cs{authorsaddresses}\marg{contact addresses}, for example,
+% \begin{verbatim}
+% \authorsaddresses{%
+% Authors' addresses: G.~Zhou, Computer Science Department, College of
+% William and Mary, 104 Jameson Rd, Williamsburg, PA 23185, US;
+% V.~B\'eranger, Inria Paris-Rocquencourt, Rocquencourt, France;

+%
+% \DescribeMacro{\titlenote}%
+% \DescribeMacro{\subtitlenote}%
+% \DescribeMacro{\authornote}%
+% While the command \cs{thanks} generates a note without a footnote
+% mark, sometimes the authors might need notes more tightly connected
+% to the title, subtitle or author. The commands \cs{titlenote},
+% \cs{subtitlenote} and \cs{authornote} that follow the corresponding
+% commands (\cs{title}, \cs{subtitle} and \cs{author}) generate such
+% notes. For example,
+% \begin{verbatim}
+% \title{This is a title}
+% \titlenote{This is a titlenote}
+% \author{A. U. Thor}
+% \authornote{This is an authornote}
+% \end{verbatim}
+%
+% Please never use a \cs{footnote} inside an \cs{author} or \cs{title}
+% command since this confuses the metadata extraction software. (Actually
+% these commands now produce errors.)
+%
+% \DescribeMacro{\authornotemark}%
+% Sometimes one may need to have the same footnote connected to
+% several authors. The command \cs{authornotemark}\oarg{number} adds
+% just the footnote mark, for example,
+% \begin{verbatim}
+% \author{A. U. Thor}
+% \authornote{Both authors contributed equally to the paper}
+% ...
+% \author{A. N. Other}
+% \authornotemark[1]
+% \end{verbatim}
+% The correct numbering of these marks is the responsibility of the
+% user.
+%
+% \DescribeMacro{\acmVolume}%
+% \DescribeMacro{\acmNumber}%
+% \DescribeMacro{\acmArticle}%
+% \DescribeMacro{\acmYear}%
+% \DescribeMacro{\acmMonth}%
+% The macros \cs{acmVolume}, \cs{acmNumber}, \cs{acmArticle},
+% \cs{acmYear} and \cs{acmMonth} are inserted by the editor and set
+% the journal volume, issue, article number, year and month
+% corrspondingly. The arguments of all these commands, including
+% \cs{acmMonth}, is numerical. For example,
+% \begin{verbatim}
+% \acmVolume{9}
+% \acmNumber{4}
+% \acmArticle{39}
+% \acmYear{2010}
+% \acmMonth{3}
+% \end{verbatim}
+% Note that \cs{acmArticle} is used not only for journals but also
+% for some conference proceedings.
+%
+% \DescribeMacro{\acmArticleSeq}%
+% The articles in the same issue of a journal have a \emph{sequence
+% number}. It is used to vertically position the black blob on the first
+% page of some formats. By default it is the same as the article number,
+% but the command \cs{acmArticleSeq}\marg{n} can be used to change it:
+% \begin{verbatim}
+% \acmArticle{39} % The sequence number will be 39 by default
+% \acmArticleSeq{5} % We redefine it to 5
+% \end{verbatim}
+% Setting this number to zero suppresses the blob.
+%
+% \DescribeMacro{\acmSubmissionID}%
+% If your paper got a Submission~ID from the Conference Management
+% System, put it here:
+% \begin{verbatim}
+% \acmSubmissionID{123-A56-BU3}
+% \end{verbatim}
+%
+%
+% \DescribeMacro{\acmPrice}%
+% The macro \cs{acmPrice}\marg{price} sets the price for the article,
+% for example,
+% \begin{verbatim}
+% \acmPrice{25.00}
+% \end{verbatim}
+% Note that you do not need to put the dollar sign here, just the
+% amount. By default the price is \$15.00, unless the copyright is
+% set to |usgov|, |rightsretained|, |iw3c2w3|, or |iw3c2w3g|, when it
+% is suppressed. Note that to override the defaults you need to set
+% the price \emph{after} the \cs{setcopyright} command. Also, the
+% command |\acmPrice{}| suppresses the printing of the price.
+%
+% \DescribeMacro{\acmISBN}%
+% Book-like volumes have ISBN numbers attached to them. The macro
+% \cs{acmISBN}\marg{ISBN} sets it. Normally it is set by the
+% typesetter, for example,
+% \begin{verbatim}
+% \acmISBN{978-1-4503-3916-2}
+% \end{verbatim}
+% Setting it to the empty string, as |\acmISBN{}|, suppresses printing the
+% ISBN.
+%
+% \DescribeMacro{\acmDOI}%
+% The macro \cs{acmDOI}\marg{DOI} sets the DOI of the article, for
+% example,
+% \begin{verbatim}
+% \acmDOI{10.1145/9999997.9999999}
+% \end{verbatim}
+% It is normally set by the typesetter. Setting it to the empty
+% string, as |\acmDOI{}|, suppresses the DOI.
+%
+%
+% \DescribeMacro{\acmBadgeR}%
+% \DescribeMacro{\acmBadgeL}%
+% Some conference articles get special distinctions, for example, the
+% artifact evaluation for PPoPP~2016
+% (see~\url{http://ctuning.org/ae/ppopp2016.html}). These articles
+% display special badges supplied by the conference organizers. This
+% class provides commands to add these badges:
+% \cs{acmBadgeR}\oarg{url}\marg{graphics} and
+% \cs{acmBadgeL}\oarg{url}\marg{graphics}. The first command puts the
+% badge to the right of the title, and the second one---to the left.
+% The arguments have the following meaning: \oarg{url}, if provided,
+% sets the link to the badge authority in the screen version, while
+% \marg{graphics} sets the graphics file with the badge image. The
+% file must be a cropped square, which is scaled to a standard size in
+% the output. For example, if the badge image is |ae-logo.pdf|, the
+% command is
+% \begin{verbatim}
+% \acmBadgeR[http://ctuning.org/ae/ppopp2016.html]{ae-logo}
+% \end{verbatim}
+%
+%
+%
+% \DescribeMacro{\startPage}%
+% The macro \cs{startPage}\marg{page} sets the first page of the
+% article in a journal or book. It is used by the typesetter.
+%
+%
+% \DescribeMacro{\terms}%
+% \DescribeMacro{\keywords}%
+% The command
+% \cs{keywords}\marg{keyword, keyword,\ldots} sets keywords for the
+% article. They must be
+% separated by commas, for example,
+% \begin{verbatim}
+% \keywords{wireless sensor networks, media access control,
+% multi-channel, radio interference, time synchronization}
+% \end{verbatim}
+%
+% \DescribeEnv{CCSXML}%
+% \DescribeMacro{\ccsdesc}%
+% ACM publications are classified according to the ACM Computing
+% Classification Scheme (CCS). CCS codes are used both in the typeset
+% version of the publications \emph{and} in the metadata in various
+% databases. Therefore you need to provide both \TeX\ commands and XML
+% metadata with the paper.
+%
+% The tool at \url{http://dl.acm.org/ccs.cfm} can be used to generate
+% CCS codes. After you select the topics, click on ``Generate CCS
+% codes'' to get results like the following:
+% \begin{verbatim}

+% \end{verbatim}
+%
+% You just need to copy this code and paste it in your paper anywhere
+% before \verb|\maketitle|.
+%
+% CCS Concepts and user-defined keywords are required for all articles
+% over two pages in length, and are optional for one- and two-page
+% articles (or abstracts).
+%
+% \DescribeMacro{\setcopyright}
+% There are several possibilities for the copyright of the papers
+% published by the ACM: the authors may transfer the rights to the ACM,
+% license them to the ACM, some or all authors might be employees of the
+% US or Canadian governments, etc. Accordingly the command
+% \verb|\setcopyright{...}| is introduced. Its argument is the
+% copyright status of the paper, for example,
+% \verb|\setcopyright{acmcopyright}|. The possible values for this
+% command are listed in Table~\ref{tab:setcopyright}. This command
+% must be placed in the preamble, before |\begin{document}|.
+%
+% \begin{table}
+% \centering
+% \caption{Parameters for the \texttt{\textbackslash setcopyright} command}
+% \label{tab:setcopyright}
+% \begin{tabularx}{\textwidth}{lX}
+% \toprule

+% \bottomrule
+% \end{tabularx}
+% \end{table}
+% The ACM submission software should generate the right command for you
+% to paste into your file.
+%
+%
+% \DescribeMacro{\copyrightyear}%
+% Each copyright statement must have the year of copyright. By
+% default it is the same as \cs{acmYear}, but you can override this
+% using the macro \cs{copyrightyear}, e.g.,
+% \begin{verbatim}
+% \acmYear{2016}
+% \copyrightyear{2015}
+% \end{verbatim}
+%
+% There is a special case for a personal copy that the authors may be
+% allowed to generate for their use or a posting on a personal site
+% (check the instructions for the specific journal or conference for
+% the details). The document option |authorversion=true| produces a
+% special form of the copyright statement for this case. Note that
+% you still need the \cs{setcopyright} command and (optionally)
+% \cs{copyrightyear} command to tell \TeX\ about the copyright owner and
+% year. Also, you should be aware that due to the different sizes of
+% the permssion blocks for the printed version and authors' version,
+% the page breaks might be different between them.
+%
+% \DescribeEnv{abstract}%
+% The environment |abstract| must \emph{precede} the \cs{maketitle}
+% command. Again, this is different from the standard \LaTeX.
+% Putting |abstract| after \cs{maketitle} will trigger an error.
+%
+%
+% \DescribeEnv{teaserfigure}%
+% A special kind of figure is used for many two-column conference
+% proceedings. This figure is placed just after the authors but
+% before the main text. The environment |teaserfigure| is used for these
+% figures. This environment must be used \emph{before}
+% \cs{maketitle}, for example,
+% \begin{verbatim}
+% \begin{teaserfigure}
+% \includegraphics[width=\textwidth]{sampleteaser}
+% \caption{This is a teaser}
+% \label{fig:teaser}
+% \end{teaserfigure}
+% \end{verbatim}
+%
+%
+% \DescribeMacro{\settopmatter}%
+% Some information in the top matter is printed for certain journals
+% or proceedings and suppressed for others. You can override these
+% defaults using the command \cs{settopmatter}\marg{settings}. The
+% settings and their meanings are listed in
+% Table~\ref{tab:settopmatter}. For example,
+% \begin{verbatim}
+% \settopmatter{printacmref=false, printccs=true, printfolios=true}
+% \end{verbatim}
+% The parameter |authorsperrow| requires some explanation. In
+% conference proceedings authors' information is typeset in boxes,
+% several boxes per row (see |sample-sigconf.pdf|,
+% |sample-sigplan.pdf|, etc.). The number of boxes per row is
+% determined automatically. If you want to override this,
+% you can do it using this parameter, for example,
+% \begin{verbatim}
+% \settopmatter{authorsperrow=4}
+% \end{verbatim}
+% However, in most cases you should \emph{not} do this and should use the
+% default settings. Setting |authorsperrow| to $0$ will revert it to the
+% default settings.
+%
+% The parameter |printacmref| specifies whether to print the ACM
+% bibliographic entry (default), or not. Note that this entry is
+% required for all articles over one page in length, and is optional
+% for one-page articles (abstracts).
+%
+% \begin{table}
+% \centering
+% \caption{Settings for the \cs{settopmatter} command}
+% \label{tab:settopmatter}
+% \begin{tabularx}{\textwidth}{llX}

+% |printccs| & true/false & Whether to print CCS categories\\
+% |printacmref| & true/false & Whether to print the ACM bibliographic

+% (folios)\\
+% |authorsperrow| & numeric & Number of authors per row for the title
+% page in
+% conference proceedings formats\\
+% \bottomrule
+% \end{tabularx}
+% \end{table}
+%
+%
+% \DescribeMacro{\received}%
+% The command \cs{received}\oarg{stage}\marg{date} sets the history of
+% the publication. The~\oarg{stage} argument is optional; the default
+% is |Received| for the first date and |revised| for the subsequent
+% ones. For example,
+% \begin{verbatim}
+% \received{February 2007}
+% \received[revised]{March 2009}
+% \received[accepted]{June 2009}
+% \end{verbatim}
+%
+%
+% \DescribeMacro{\maketitle}%
+% The macro \cs{maketitle} must be the last command in the top-matter
+% group. That is it must follow the commands defined in this section.
+%
+%
+% \DescribeMacro{\shortauthors}%
+% \emph{After} the command \cs{maketitle}, the macro \cs{shortauthors}
+% stores the names of the authors for the running head. You can
+% redefine it if the list of author's name is too long, e.g.,
+% \begin{verbatim}
+% \maketitle
+% \renewcommand{\shortauthors}{Zhou et al.}
+% \end{verbatim}
+%
+%
+%\subsection{Algorithms}
+%\label{sec:ug_algorithms}
+%
+% There are now several good packages for typesetting
+% algorithms~\cite{Fiorio15, Brito09, Heinz15}, and the authors are
+% free to choose their favorite one.
+%
+%
+%
+%\subsection{Figures and tables}
+%\label{sec:ug_floats}
+%
+% The new ACM styles use the standard \LaTeX\ interface for figures and
+% tables. There are some important items to be aware of, however.
+%
+% \begin{enumerate}
+% \item The captions for figures must be entered \emph{after} the
+% figure bodies and for tables \emph{before} the table bodies.
+% \item The ACM uses the standard types for figures and tables and adds
+% several new ones. In total there are the following types:
+% \begin{description}
+% \item[figure, table:] a standard figure or table taking a full text
+% width in one-column formats and one column width in two-column formats.
+% \item[figure*, table*] in two-column formats, a special figure or
+% table taking a full text width.
+% \item[teaserfigure:] a special figure before \cs{maketitle}.
+% \end{description}
+%
+% \item Accordingly, when scaling images, one should use the
+% following sizes:
+% \begin{enumerate}
+% \item For |teaserfigure|, |figure| in one-column mode or |figure*| in
+% two-column mode, use \cs{textwidth}. In one-column mode, you can also
+% use \cs{columnwidth}, which coincides with \cs{textwidth} in this
+% case.
+% \item For |figure| in two-column mode, use \cs{columnwidth}.
+% \end{enumerate}
+%
+% \end{enumerate}
+%
+% It is strongly recommended to use the package |booktabs|~\cite{Fear05}
+% and follow its main principles of typography with respect to tables:
+% \begin{enumerate}
+% \item Never, ever use vertical rules.
+% \item Never use double rules.
+% \end{enumerate}
+% It is also a good idea not to overuse horizontal rules.
+%
+% For table \emph{footnotes} you have several options described in the TeX
+% FAQ~\cite{TeXFAQ}. The simplest one is to use a \cs{minipage}
+% environment:
+% \begin{verbatim}
+% \begin{table}
+% \caption{Simulation Configuration}
+% \label{tab:conf}
+% \begin{minipage}{\columnwidth}
+% \begin{center}
+% \begin{tabular}{ll}
+% \toprule
+% TERRAIN\footnote{This is a table footnote. This is a
+% table footnote. This is a table footnote.} &
+% (200\,m$\times$200\,m) Square\\
+% Node Number & 289\\
+% Node Placement & Uniform\\
+% Application & Many-to-Many/Gossip CBR Streams\\
+% Payload Size & 32 bytes\\
+% Routing Layer & GF\\
+% MAC Layer & CSMA/MMSN\\
+% Radio Layer & RADIO-ACCNOISE\\
+% Radio Bandwidth & 250Kbps\\
+% Radio Range & 20m--45m\\
+% \bottomrule
+% \end{tabular}
+% \end{center}
+% \bigskip
+% \footnotesize\emph{Source:} This is a table
+% sourcenote. This is a table sourcenote. This is a table
+% sourcenote.
+%
+% \emph{Note:} This is a table footnote.
+% \end{minipage}
+% \end{table}
+% \end{verbatim}
+%
+%
+% Tables and figures are by default centered. However, in some cases
+% (for example, when you use several subimages per figure) you may
+% need to override this. A good way to do so is to put the contents
+% into a \cs{minipage} of the width \cs{columnwidth}.
+%
+%
+%\subsection{Descriptions of images}
+%\label{sec:descriptions}
+%
+% \DescribeMacro{\Description}%
+% Some readers of ACM publications might be visually challenged.
+% These readers might use a voice-over software to read aloud the
+% papers. It is important to provide them a description of each
+% image used in the paper.
+%
+% The command \cs{Description}\oarg{short description}\marg{long
+% description} should be placed inside every \texttt{figure},
+% \texttt{teaserfigure} or \texttt{marginfigure} environment to
+% provide a description of the image(s) used in the figure. Unlike
+% \cs{caption}, which is used alongside the image, \cs{Description} is
+% intended to be used instead of the image, for example,
+% \begin{verbatim}
+% \begin{figure}
+% \centering
+% \includegraphics{voltage}
+% \Description{A bell-like histogram centered at $0.5$~V with most
+% measurements between $0.2$~V and $0.8$~V}
+% \caption{Histogram of the measurements of voltage}
+% \label{fig:voltage}
+% \end{figure}
+% \end{verbatim}
+% At present the lack of descriptions generates a warning at
+% compilation.
+%
+%\subsection{Theorems}
+%\label{sec:ug_theorems}
+%
+% The ACM classes define two theorem styles and several pre-defined
+% theorem environments:
+% \begin{description}
+% \item[acmplain:] this is the style used for
+% |theorem|,
+% |conjecture|,
+% |proposition|,
+% |lemma| and
+% |corollary|, and
+% \item[acmdefinition:] this is the style used for
+% |example| and
+% |definition|.
+% \end{description}
+%
+%
+% These environments are defined by default. In the unusual
+% circumstance that a user does not wish to have these environments
+% defined, the option |acmthm=false| in the preamble will suppress
+% them.
+%
+%\subsection{Online-only and offline-only material}
+%\label{sec:ug_screen}
+%
+% \DescribeEnv{printonly}%
+% \DescribeEnv{screenonly}%
+% Some supplementary material in ACM publications is put online but
+% not in the printed version. The text inside the environment
+% |screenonly| will be typeset only when the option |screen| (see
+% Section~\ref{sec:invocation}) is set to |true|. Conversely, the
+% text inside the environment |printonly| is typeset only when this
+% option is set to |false|. For example,
+% \begin{verbatim}
+% \section{Supplementary materials}
+%
+% \begin{printonly}
+% Supplementary materials are available in the online version of this paper.
+% \end{printonly}
+%
+% \begin{screenonly}
+% (The actual supplementary materials.)
+% \end{screenonly}
+% \end{verbatim}
+%
+% We use the |comment| package for typesetting this code, so
+% |\begin| and |\end| should start on a line of their own with
+% no leading or trailing spaces.
+%
+%\subsection{Note about anonymous mode}
+%\label{sec:ug_anonymous}
+%
+% \DescribeEnv{anonsuppress}%
+% When the option |anonymous| is selected, \TeX\ suppresses author
+% information (including the number of authors) for a blind review.
+% However, sometimes the information identifying the authors may be
+% present in the body of the paper. For example,
+% \begin{verbatim}
+% \begin{anonsuppress}
+% This is the continuation of the previous work by the author
+% \cite{prev1, prev2}.
+% \end{anonsuppress}
+% \end{verbatim}
+%
+% As for the |printonly| and |screenonly| environments,
+% |\begin{anonsuppress}| and |\end{anonsuppress}| should start on a
+% line of their own with no leading or trailing spaces.
+%
+%\subsection{Acknowledgments}
+%\label{sec:ug_acks}
+%
+% The traditional ``Acknowledgments'' section is conventionally used
+% to thank persons and granting agencies for their help and support.
+% However, there are several important considerations about this
+% section.
+%
+% First, in anonymous mode this section must be omitted: it gives
+% too much information to reviewers. Second, data about
+% grants is extracted and stored separately by the postprocessing
+% software. ACM classes provide facilities for both these tasks.
+%
+% \DescribeEnv{acks}%
+% The environment |acks| starts an unnumbered section
+% ``Acknowledgments'' unless the anonymous mode is chosen. Put all
+% thanks inside this environment.
+%
+% As for the |printonly| and |screenonly| environments,
+% |\begin{acks}| and |\end{acks}| should start on a
+% line of their own with no leading or trailing spaces.
+%
+% \DescribeMacro{\grantsponsor}%
+% \DescribeMacro{\grantnum}%
+% All financial support \emph{must} be listed using the commands
+% \cs{grantsponsor} and \cs{grantnum}. These commands tell the
+% postprocessing software about the granting organization and
+% grant. The format of these commands is the following:
+% \begin{quote}
+% \cs{grantsponsor}\marg{sponsorID}\marg{name}\marg{url}\\
+% \cs{grantnum}\oarg{url}\marg{sponsorID}\marg{number}.
+% \end{quote}
+% Here \marg{sponsorID} is the unique ID used to match grants to
+% sponsors, \marg{name} is the name of the sponsor, \marg{url} is its
+% URL, and \marg{number} is the grant number. The \marg{sponsorID} of
+% the \cs{grantnum} command must correspond to the \marg{sponsorID} of a
+% \cs{grantsponsor} command. Some awards have their own web pages,
+% which you can include using the optional argument of the \cs{grantnum}
+% command.
+%
+% At present \marg{sponsorID} is chosen by the authors and can be an
+% arbitrary key in the same way the label of a \cs{cite} is arbitrarily
+% chosen. There might be a change to this policy if the ACM decides to
+% create a global database of sponsoring organizations.
+%
+% Example:
+% \begin{verbatim}
+% \begin{acks}
+% The authors would like to thank Dr. Yuhua Li for providing the
+% matlab code of the \textit{BEPS} method.
+%
+% The authors would also like to thank the anonymous referees for
+% their valuable comments and helpful suggestions. This work is
+% supported by the \grantsponsor{GS501100001809}{National Natural
+% Science Foundation of
+% China}{https://doi.org/10.13039/501100001809} under Grant
+% No.:~\grantnum{GS501100001809}{61273304}
+% and~\grantnum[http://www.nnsf.cn/youngscientists]{GS501100001809}{Young
+% Scientists' Support Program}.
+% \end{acks}
+% \end{verbatim}
+%
+%
+%\subsection{Bibliography}
+%\label{sec:ug_bibliography}
+%
+% The ACM uses the |natbib| package for formatting references and
+% the Bib\TeX\ style file \path{ACM-Reference-Format.bst} for Bib\TeX\
+% processing. You can disable loading of |natbib| using the
+% option |natbib=false| in \cs{documentclass}. However, it is not
+% recommended, as well as the use of Bib\TeX\ styles other than
+% \path{ACM-Reference-Format.bst}, and may delay the processing of the
+% manuscript.
+%
+%
+% \DescribeMacro{\citestyle}%
+% If you use |natbib|, you can select one of two predefined citation
+% styles using the command \cs{citestyle}: the author-year format
+% |acmauthoryear| or the numeric format |acmnumeric|. For example,
+% \begin{verbatim}
+% \citestyle{acmauthoryear}
+% \end{verbatim}
+% Note that numeric citations are the default mode for most formats.
+%
+% \DescribeMacro{\setcitestyle}%
+% You can further customize |natbib| using
+% the \cs{setcitestyle} command, for example,
+% \begin{verbatim}
+% \setcitestyle{numbers,sort&compress}
+% \end{verbatim}
+%
+% One of the more common versions is
+% \begin{verbatim}
+% \setcitestyle{nosort}
+% \end{verbatim}
+% It is useful if you do not like the way |natbib| sorts citation
+% lists.
+%
+% If you use |natbib|, then commands like \cs{citep} and
+% \cs{citeauthor} are automatically supported. The command
+% \cs{shortcite} is the same as \cs{cite} in numerical mode and cites
+% the year in author-date mode.
+%
+% Note that before version~1.48 the command \cs{citeyear} put the year
+% in parentheses. In version~1.48 and later it produces just the
+% year; the command \cs{citeyearpar} can be used to emulate its old
+% behavior.
+%
+% There are several customized \BibTeX\ entry types and fields in the ACM
+% style file \path{ACM-Reference-Format.bst} that you may want to be
+% aware of.
+%
+% The style supports the fields \path{doi} and \path{url}, for example,
+% \begin{verbatim}
+% doi = "10.1145/1188913.1188915",
+% url = "http://ccrma.stanford.edu/~jos/bayes/bayes.pdf",
+% \end{verbatim}
+%
+% The style supports the arXiv-recommended fields \path{eprint} and
+% (optionally) \path{primaryclass}, for example,
+% \begin{verbatim}
+% eprint = "960935712",
+% primaryclass = "cs",
+% \end{verbatim}
+% See the examples at \url{http://arxiv.org/hypertex/bibstyles/}.
+%
+% There are several special entry types. Types \path{online} and
+% \path{game} are used for Web pages and games, for example,
+% \begin{verbatim}
+% @online{Thornburg01,
+% author = "Harry Thornburg",
+% year = "2001",
+% title = "Introduction to Bayesian Statistics",
+% url = "http://ccrma.stanford.edu/~jos/bayes/bayes.html",
+% month = mar,
+% lastaccessed = "March 2, 2005",
+% }
+% \end{verbatim}
+% Entry types \path{artifactsoftware}, \path{artifactdataset}
+% (with synonyms \path{software} and \path{dataset}) can be used to
+% cite software artifacts and datasets, for example,
+% \begin{verbatim}
+% @ArtifactSoftware{R,
+% title = {R: A Language and Environment for Statistical Computing},
+% author = {{R Core Team}},
+% organization = {R Foundation for Statistical Computing},
+% address = {Vienna, Austria},
+% year = {2019},
+% url = {https://www.R-project.org/},
+%}
+% @ArtifactDataset{UMassCitations,
+% author = {Sam Anzaroot and Andrew McCallum},
+% title = {{UMass} Citation Field Extraction Dataset},
+% year = 2013,
+% url =
+% {http://www.iesl.cs.umass.edu/data/data-umasscitationfield},
+% lastaccessed = {May 27, 2019}
+% }
+% \end{verbatim}
+%
+%
+% For these entry types you can use the \path{lastaccessed} field to add
+% the access date for the URL.
+%
+%
+%
+% There are two ways to enter video or audio sources in the
+% bibliograpy corresponding to two different possibilies. For
+% standalone sources available online, you can use an \path{online}
+% entry and set its \path{howpublished} field. For example,
+% \begin{verbatim}
+% @online{Obama08,
+% author = "Barack Obama",
+% year = "2008",
+% title = "A more perfect union",
+% howpublished = "Video",
+% day = "5",
+% url = "http://video.google.com/videoplay?docid=6528042696351994555",
+% month = mar,
+% lastaccessed = "March 21, 2008",
+% }
+% \end{verbatim}
+%
+% For sources available as attachments to conference proceedings
+% and similar documents, you can use the usual \path{inproceedings}
+% entry type and set its \path{howpublished} field:
+% \begin{verbatim}
+% @Inproceedings{Novak03,
+% author = "Dave Novak",
+% title = "Solder man",
+% booktitle = "ACM SIGGRAPH 2003 Video Review on Animation theater Program",
+% year = "2003",
+% publisher = "ACM Press",
+% address = "New York, NY",
+% pages = "4",
+% month = "March 21, 2008",
+% doi = "10.9999/woot07-S422",
+% howpublished = "Video",
+% }
+% \end{verbatim}
+%
+% Sometimes you need to cite a complete issue of a journal. The
+% \path{periodical} entry type is intended for this:
+% \begin{verbatim}
+% @periodical{JCohen96,
+% key = "Cohen",
+% editor = "Jacques Cohen",
+% title = "Special issue: Digital Libraries",
+% journal = "Communications of the {ACM}",
+% volume = "39",
+% number = "11",
+% month = nov,
+% year = "1996",
+% }
+% \end{verbatim}
+%
+% If you do not know the year of publication, the style will add
+% ``[n.\,d.]'' (for ``no date'') to the entry.
+%
+% If you do not know the author (this is often the case for online
+% entries), use the |key| field to add a key for sorting and citations,
+% for example,
+% \begin{verbatim}
+% @online{TUGInstmem,
+% key = {TUG},
+% year = 2017,
+% title = "Institutional members of the {\TeX} Users Group",
+% url = "http://wwtug.org/instmem.html",
+% lastaccessed = "May 27, 2017",
+% }
+% \end{verbatim}
+%
+% A note about sorting. The current ACM bibliography styles always
+% sort the entries according to authors names and publication year.
+% There is a controversy about sorting names with ``von'' or ``van''
+% part: should Ludwig van Beethoven be sorted under ``V'' or under
+% ``B''? The American practice is to use ``van'' in sorting, i.e. to
+% file van Beethoven under ``V''. However, some authorities recommend
+% to sort Dutch persons according to their last names (see
+% e.g. \url{https://www.ifla.org/files/assets/cataloguing/pubs/names-of-persons_1996.pdf}).
+% While I do not want to take a part in this dispute, I would like to
+% point to the old ``noopsort'' trick by Oren Patashnik. Add to the
+% \texttt{.bib} file the line
+% \begin{verbatim}
+% @PREAMBLE{"\providecommand{\noopsort}[1]{}"}
+% \end{verbatim}
+% and then encode the author as
+% \begin{verbatim}
+% author = {Ludwig {\noopsort{Beethoven}}van Beethoven},
+% \end{verbatim}
+% This will make the author to be sorted as ``Beethoven'' rather than
+% ``van Beethoven''.
+%
+%\subsection{Colors}
+%\label{sec:ug_colors}
+%
+% While printed ACM publications are usually black and white, |screen|
+% mode allows the use of colors. The ACM classes pre-define several
+% colors according to~\cite{ACMIdentityStandards}: |ACMBlue|,
+% |ACMYellow|, |ACMOrange|, |ACMRed|, |ACMLightBlue|, |ACMGreen|,
+% |ACMPurple| and |ACMDarkBlue|. You can use them in color
+% assignments.
+%
+% The ACM provides the following recommendation on color use.
+%
+% The most accessible approach would be to ensure that your article is
+% still readable when printed in greyscale. The most notable reasons
+% for this are:
+% \begin{enumerate}
+% \item The most common type of inherited Color Vision Deficiency
+% (CVD) is red-green (in which similar-brightness colors that differ
+% only in their amounts of red or green are often confused), and it
+% affects up to 8\% of males and 0.5\% of females of Northern European
+% descent.
+% \item The most common type of acquired Color Vision Deficiency (CVD)
+% is blue-yellow (including mild cases for many older adults).
+% \item Most printing is in black and white.
+% \item Situational impairments (e.g., bright sunlight shining on a
+% mobile screen) tend to reduce the entire color gamut, reducing color
+% discriminability.
+% \end{enumerate}
+%
+% \textbf{Note:} It is \emph{not} safe to encode information using
+% only variations in color (i.e., only differences in hue and/or
+% saturation) as there is bound to be someone affected!
+%
+% To ensure that you are using the most accessible colors, the ACM
+% recommends that you choose sets of colors to help ensure suitable
+% variations in when printed in greyscale by using either of the following tools:
+% \begin{enumerate}
+% \item ColourBrewer: \url{http://colorbrewer2.org/}
+% \item ACE: The Accessible Colour Evaluator:
+% \url{http://daprlab.com/ace/} for designing WCAG 2.0 compliant
+% palettes.
+% \end{enumerate}
+%
+%
+%\subsection{Other notable packages and typographic remarks}
+%\label{sec:ug_other}
+%
+% Several other packages are recommended for specialized tasks.
+%
+% The package |subcaption|~\cite{Sommerfeldt13:Subcaption} is
+% recommended for complex figures with several subplots or subfigures
+% that require separate subcaptioning. The packages
+% |nomencl|~\cite{Nomencl} and
+% |glossaries|~\cite{Talbot16:Glossaries} can be used for the
+% automatic creation of the lists of symbols and concepts used.
+%
+%
+% By default |acmart| prevents all widows and orphans (i.e., lonely
+% lines at the beginning or end of the page) and hyphenation at
+% the end of the page. This is done by the rather strict settings
+% \begin{verbatim}
+% \widowpenalty=10000
+% \clubpenalty=10000
+% \brokenpenalty=10000
+% \end{verbatim}
+% However, this may lead to frustrating results when the authors must
+% obey a page limit. Setting these penalties to smaller values may
+% help if you absolutely need to.
+%
+% Another problem might be the too strict line breaking rules. Again,
+% a strategically placed \cs{sloppy} command or putting the
+% problematic paragraph inside \texttt{sloppypar} environment might
+% help---but beware, the results might be, well, sloppy.
+%
+% Note that the uppercasing in section titles is done using
+% the |textcase| package~\cite{Carlisle04:Textcase}, so the command
+% \cs{NoCaseChange} inside the title may help to prevent extraneous
+% uppercasing.
+%
+%
+%
+%\subsection{Disabled or forbidden commands}
+%\label{sec:ug_disabled}
+%
+% The goal of |acmart| package is to provide a uniform look and feel
+% for ACM publications. Accordingly, a number of commands is
+% forbidden or disabled in |acmart|.
+%
+% You may \emph{not} put several authors or several e-mails into a
+% \cs{author} or \cs{email} command. This may lead to errors or
+% warning.
+%
+% You cannot change \cs{baselinestretch} in your document: this
+% produces an error.
+%
+% You should not abuse the command \cs{vspace}: this command may
+% disturb the typesetting of ACM papers.
+%
+% You should not load |amssymb| package since the package |acmart|
+% defines the corresponding symbols itself.
+%
+%\subsection{Notes for wizards}
+%\label{sec:ug_preload}
+%
+% Sometimes you need to change the behavior of |acmart|. The
+% usual way to do this is to redefine commands in the preamble.
+% However, these definitions are executed \emph{after} |acmart| is
+% loaded and certain decisions are made. This presents a number of
+% problems.
+%
+% For example, one may want to use the |titletoc| package with |acmart|.
+% This package should be loaded before |hyperref|. However, since
+% |acmart| loads |hyperref| itself, the line |\usepackage{titletoc}|
+% in the preamble will lead to grief (see
+% \url{http://tex.stackexchange.com/questions/357265/using-titletoc-with-acm-acmart-style}).
+%
+% Another example is passing options to a package. Suppose you want to
+% use the |dvipsnames| option of the |xcolor| package. Normally you cannot do
+% this because |acmart| loads this package itself without options.
+%
+% The file |acmart-preload-hook.tex| can be used to solve these
+% problems. If this file exists, it will be processed before any other
+% package. You can use this file to load packages or pass options to
+% them. For example, if you put in this file
+% \begin{verbatim}
+% \let\LoadClassOrig\LoadClass
+% \renewcommand\LoadClass[2][]{\LoadClassOrig[#1]{#2}%
+% \usepackage{titletoc}}
+% \end{verbatim}
+% then |titletoc| will be loaded before |hyperref|. If you put in
+% this file
+% \begin{verbatim}
+% \PassOptionsToPackage{dvipsnames}{xcolor}
+% \end{verbatim}
+% you will pass |dvipsnames| to |xcolor|.
+%
+% \textbf{Important note.} This hook makes it too easy to create a
+% manuscript that is not acceptable by the ACM. It is even easier to
+% create a file that cannot be compiled. So please do not use it
+% \emph{unless you know what you are doing.} And if you use it,
+% \emph{do not ask for support.} If you decide to use this hook, you
+% are on your own.
+%
+% \DescribeMacro{\AtBeginMaketitle}%
+% Another hook is \cs{AtBeginMaketitle}. The commands in this hook
+% are executed before \cs{maketitle}, for example,
+% \begin{verbatim}
+% \AtBeginMaketitle{\acmPrice{125.00}}
+% \end{verbatim}

+%\subsection{A note about \texttt{sigchi-a} format}
+%\label{sec:sigchi-a}
+%
+% Starting in Spring 2020 ACM retired SIGCHI Extended Abstract format
+% (|sigchi-a|). ACM will not, under any circumstances, accept
+% documents in this format for publication and will not offer
+% technical support to the authors who use this template.
+%
+% You may use this format in the |nonacm| mode only, as in
+% \begin{verbatim}
+% \documentclass[sigchi-a, nonacm]{acmart}
+% \end{verbatim}
+%
+%
+%
+% \DescribeEnv{sidebar}%
+% \DescribeEnv{marginfigure}%
+% \DescribeEnv{margintable}%
+% This format has large margin uses for special figures and
+% tables. This package provides three environments for this with
+% optional captions:
+% \begin{description}
+% \item[sidebar:] textual information in the margin,
+% \item[marginfigure:] a figure in the margin,
+% \item[margintable:] a table in the margin.
+% \end{description}
+%
+% The environments |figure| and |table| produce figures and tables
+% with the width of the text column. The environments |figure*| and
+% |table*| produce ``wide'' figures and tables, which take a large
+% part of the margin.
+%
+% The horizontal sizes of figures are:
+% \begin{enumerate}
+% \item |figure|: \cs{columnwidth},
+% \item |marginfigure|: \cs{marginparwidth},
+% \item |figure*|: \cs{fulltextwidth}.

+%
+% \begin{macro}{\ACM@NRadjust}
+% \changes{v1.54}{2018/06/17}{Added macro}
+% Ross Moore's macro.
+% \begin{quotation}
+% Initially |\ACM@sect@format@| just passes through its |#1|
+% argument unchanged.
+% When a sectioning macro such as |\section| occurs, the
+% |\ACM@NRadjust| redefines |\ACM@sect@format@| to expand into the
+% styling commands; e.g., |\@secfont|.
+% Then |\Sectionformat| is temporarily redefined to produce
+% |\realSectionformat{\ACM@sect@format{#1}}{#2}|, which ultimately
+% becomes |\Sectionformat{\@secfont{#1}}{#2}|.
+% This is done to allow |\Sectionformat| to be variable, as may be
+% needed in particular circumstances. Its current expansion is saved
+% as |\realSectionformat| which is used with the modified 1st argument,
+% then |\Sectionformat| is reverted to its former expansion.
+%
+% To style the section-number, the line |#1{}| is used at the end of
+% |\ACM@NRadjust|. This imposes style-changing commands for fonts and
+% sizes, but any |\MakeUppercase| acts on just the |{}|. It's a bit hacky,
+% by essentially assuming that only numbers occur here, not letters to
+% be case-changed. (This should be acceptable in a class-file, as it
+% ought to be possible to change the case elsewhere, if that was ever
+% desired.) Also, it can result in |\@adddotafter| being called too
+% soon, so a slight adjustment is made, via |\ACM@adddotafter|, which
+% now tests whether its argument is empty. But the coding has to allow
+% for other packages to have also patched |\@adddotafter|.

+\section{Introduction}
+In the 5th semester of their undergrad studies, BSc students from Budapest
+University of Tehchnology and Economics embark on their first journey of
+scientific research. I was always interested in and fascinated by computer
+graphics, it came naturally to choose a subject in this area. As I had little
+ hands-on experience in this field, a long time had to be dedicated
+to research and trying out different simulation methods.
+
+The first of this paper reflects this, giving an overview of considered methods,
+and other possible routes that could have been taken to implement hair
+simulation.
+
+\section{Overview of considered methods}
+
+There were mainly three methods considered, two of them being substantially
+different:
+
+
+\subsection{Mass Spring System}
+The whole idea of doing hair simulation as my project laboratory came from
+\TODO{reference Pixar article and Khan Academy video}
+
+\begin{verbatim}
+ \documentclass[STYLE]{acmart}
+\end{verbatim}
+
+\subsection{Position Based Dynamics}
+
+
+\subsection{Follow the Leader}
+The Dynamic Follow-The-Leader method outlined in \TODO{reference article}
+
+
+%%
+%% The acknowledgments section is defined using the "acks" environment
+%% (and NOT an unnumbered section). This ensures the proper
+%% identification of the section in the article metadata, and the
+%% consistent spelling of the heading.
+\begin{acks}
+ To Dr. László Szécsi, associate professor at the Computer Graphics Group
+ (Department of Control Engineering and Information Technology), whom I had
+ the chance to consult with during the semester.
+\end{acks}
+
+%%
+%% The next two lines define the bibliography style to be used, and
+%% the bibliography file.
+\bibliographystyle{ACM-Reference-Format}
+\bibliography{references}
+
+%%
+%% If your work has an appendix, this is the place to put it.
+\appendix
+
+\section{Supplementary development}
+
+\subsection{OBJ Reader}
+

+malesuada, quam in pulvinar varius, metus nunc fermentum urna, id
+sollicitudin purus odio sit amet enim. Aliquam ullamcorper eu ipsum

+\section{Introduction}
+ACM's consolidated article template, introduced in 2017, provides a
+consistent \LaTeX\ style for use across ACM publications, and
+incorporates accessibility and metadata-extraction functionality
+necessary for future Digital Library endeavors. Numerous ACM and
+SIG-specific \LaTeX\ templates have been examined, and their unique
+features incorporated into this single new template.
+
+If you are new to publishing with ACM, this document is a valuable
+guide to the process of preparing your work for publication. If you
+have published with ACM before, this document provides insight and
+instruction into more recent changes to the article template.
+
+The ``\verb|acmart|'' document class can be used to prepare articles
+for any ACM publication --- conference or journal, and for any stage
+of publication, from review to final ``camera-ready'' copy, to the
+author's own version, with {\itshape very} few changes to the source.
+
+\section{Template Overview}
+As noted in the introduction, the ``\verb|acmart|'' document class can
+be used to prepare many different kinds of documentation --- a
+double-blind initial submission of a full-length technical paper, a
+two-page SIGGRAPH Emerging Technologies abstract, a ``camera-ready''
+journal article, a SIGCHI Extended Abstract, and more --- all by
+selecting the appropriate {\itshape template style} and {\itshape
+ template parameters}.
+
+This document will explain the major features of the document
+class. For further information, the {\itshape \LaTeX\ User's Guide} is
+available from
+\url{https://www.acm.org/publications/proceedings-template}.
+
+\subsection{Template Styles}
+
+The primary parameter given to the ``\verb|acmart|'' document class is
+the {\itshape template style} which corresponds to the kind of publication
+or SIG publishing the work. This parameter is enclosed in square
+brackets and is a part of the {\verb|documentclass|} command:
+\begin{verbatim}
+ \documentclass[STYLE]{acmart}
+\end{verbatim}
+
+Journals use one of three template styles. All but three ACM journals
+use the {\verb|acmsmall|} template style:
+\begin{itemize}
+\item {\verb|acmsmall|}: The default journal template style.
+\item {\verb|acmlarge|}: Used by JOCCH and TAP.
+\item {\verb|acmtog|}: Used by TOG.
+\end{itemize}
+
+The majority of conference proceedings documentation will use the {\verb|acmconf|} template style.
+\begin{itemize}
+\item {\verb|acmconf|}: The default proceedings template style.
+\item{\verb|sigchi|}: Used for SIGCHI conference articles.
+\item{\verb|sigchi-a|}: Used for SIGCHI ``Extended Abstract'' articles.
+\item{\verb|sigplan|}: Used for SIGPLAN conference articles.
+\end{itemize}
+
+\subsection{Template Parameters}
+
+In addition to specifying the {\itshape template style} to be used in
+formatting your work, there are a number of {\itshape template parameters}
+which modify some part of the applied template style. A complete list
+of these parameters can be found in the {\itshape \LaTeX\ User's Guide.}
+
+Frequently-used parameters, or combinations of parameters, include:
+\begin{itemize}
+\item {\verb|anonymous,review|}: Suitable for a ``double-blind''
+ conference submission. Anonymizes the work and includes line
+ numbers. Use with the \verb|\acmSubmissionID| command to print the
+ submission's unique ID on each page of the work.
+\item{\verb|authorversion|}: Produces a version of the work suitable
+ for posting by the author.
+\item{\verb|screen|}: Produces colored hyperlinks.
+\end{itemize}
+
+This document uses the following string as the first command in the
+source file:
+\begin{verbatim}
+\documentclass[sigplan,screen]{acmart}
+\end{verbatim}
+
+\section{Modifications}
+
+Modifying the template --- including but not limited to: adjusting
+margins, typeface sizes, line spacing, paragraph and list definitions,
+and the use of the \verb|\vspace| command to manually adjust the
+vertical spacing between elements of your work --- is not allowed.
+
+{\bfseries Your document will be returned to you for revision if
+ modifications are discovered.}
+
+\section{Typefaces}
+
+The ``\verb|acmart|'' document class requires the use of the
+``Libertine'' typeface family. Your \TeX\ installation should include
+this set of packages. Please do not substitute other typefaces. The
+``\verb|lmodern|'' and ``\verb|ltimes|'' packages should not be used,
+as they will override the built-in typeface families.
+
+\section{Title Information}
+
+The title of your work should use capital letters appropriately -
+\url{https://capitalizemytitle.com/} has useful rules for
+capitalization. Use the {\verb|title|} command to define the title of
+your work. If your work has a subtitle, define it with the
+{\verb|subtitle|} command. Do not insert line breaks in your title.
+
+If your title is lengthy, you must define a short version to be used
+in the page headers, to prevent overlapping text. The \verb|title|
+command has a ``short title'' parameter:
+\begin{verbatim}
+ \title[short title]{full title}
+\end{verbatim}
+
+\section{Authors and Affiliations}
+
+Each author must be defined separately for accurate metadata
+identification. Multiple authors may share one affiliation. Authors'
+names should not be abbreviated; use full first names wherever
+possible. Include authors' e-mail addresses whenever possible.
+
+Grouping authors' names or e-mail addresses, or providing an ``e-mail
+alias,'' as shown below, is not acceptable:
+\begin{verbatim}
+ \author{Brooke Aster, David Mehldau}
+ \email{dave,judy,steve@university.edu}
+ \email{firstname.lastname@phillips.org}
+\end{verbatim}
+
+The \verb|authornote| and \verb|authornotemark| commands allow a note
+to apply to multiple authors --- for example, if the first two authors
+of an article contributed equally to the work.
+
+If your author list is lengthy, you must define a shortened version of
+the list of authors to be used in the page headers, to prevent
+overlapping text. The following command should be placed just after
+the last \verb|\author{}| definition:
+\begin{verbatim}
+ \renewcommand{\shortauthors}{McCartney, et al.}
+\end{verbatim}
+Omitting this command will force the use of a concatenated list of all
+of the authors' names, which may result in overlapping text in the
+page headers.
+
+The article template's documentation, available at
+\url{https://www.acm.org/publications/proceedings-template}, has a
+complete explanation of these commands and tips for their effective
+use.
+
+Note that authors' addresses are mandatory for journal articles.
+
+\section{Rights Information}
+
+Authors of any work published by ACM will need to complete a rights
+form. Depending on the kind of work, and the rights management choice
+made by the author, this may be copyright transfer, permission,
+license, or an OA (open access) agreement.
+
+Regardless of the rights management choice, the author will receive a
+copy of the completed rights form once it has been submitted. This
+form contains \LaTeX\ commands that must be copied into the source
+document. When the document source is compiled, these commands and
+their parameters add formatted text to several areas of the final
+document:
+\begin{itemize}
+\item the ``ACM Reference Format'' text on the first page.
+\item the ``rights management'' text on the first page.
+\item the conference information in the page header(s).
+\end{itemize}
+
+Rights information is unique to the work; if you are preparing several
+works for an event, make sure to use the correct set of commands with
+each of the works.
+
+The ACM Reference Format text is required for all articles over one
+page in length, and is optional for one-page articles (abstracts).
+
+\section{CCS Concepts and User-Defined Keywords}
+
+Two elements of the ``acmart'' document class provide powerful
+taxonomic tools for you to help readers find your work in an online
+search.
+
+The ACM Computing Classification System ---
+\url{https://www.acm.org/publications/class-2012} --- is a set of
+classifiers and concepts that describe the computing
+discipline. Authors can select entries from this classification
+system, via \url{https://dl.acm.org/ccs/ccs.cfm}, and generate the
+commands to be included in the \LaTeX\ source.
+
+User-defined keywords are a comma-separated list of words and phrases
+of the authors' choosing, providing a more flexible way of describing
+the research being presented.
+
+CCS concepts and user-defined keywords are required for for all
+articles over two pages in length, and are optional for one- and
+two-page articles (or abstracts).
+
+\section{Sectioning Commands}
+
+Your work should use standard \LaTeX\ sectioning commands:
+\verb|section|, \verb|subsection|, \verb|subsubsection|, and
+\verb|paragraph|. They should be numbered; do not remove the numbering
+from the commands.
+
+Simulating a sectioning command by setting the first word or words of
+a paragraph in boldface or italicized text is {\bfseries not allowed.}
+
+\section{Tables}
+
+The ``\verb|acmart|'' document class includes the ``\verb|booktabs|''
+package --- \url{https://ctan.org/pkg/booktabs} --- for preparing
+high-quality tables.
+
+Table captions are placed {\itshape above} the table.
+
+Because tables cannot be split across pages, the best placement for
+them is typically the top of the page nearest their initial cite. To
+ensure this proper ``floating'' placement of tables, use the
+environment \textbf{table} to enclose the table's contents and the
+table caption. The contents of the table itself must go in the
+\textbf{tabular} environment, to be aligned properly in rows and
+columns, with the desired horizontal and vertical rules. Again,
+detailed instructions on \textbf{tabular} material are found in the
+\textit{\LaTeX\ User's Guide}.
+
+Immediately following this sentence is the point at which
+Table~\ref{tab:freq} is included in the input file; compare the
+placement of the table here with the table in the printed output of
+this document.
+
+\begin{table}
+ \caption{Frequency of Special Characters}
+ \label{tab:freq}
+ \begin{tabular}{ccl}
+ \toprule
+ Non-English or Math&Frequency&Comments\\
+ \midrule
+ \O & 1 in 1,000& For Swedish names\\
+ $\pi$ & 1 in 5& Common in math\\
+ \$ & 4 in 5 & Used in business\\
+ $\Psi^2_1$ & 1 in 40,000& Unexplained usage\\
+ \bottomrule
+\end{tabular}
+\end{table}
+
+To set a wider table, which takes up the whole width of the page's
+live area, use the environment \textbf{table*} to enclose the table's
+contents and the table caption. As with a single-column table, this
+wide table will ``float'' to a location deemed more
+desirable. Immediately following this sentence is the point at which
+Table~\ref{tab:commands} is included in the input file; again, it is
+instructive to compare the placement of the table here with the table
+in the printed output of this document.
+
+\begin{table*}
+ \caption{Some Typical Commands}
+ \label{tab:commands}
+ \begin{tabular}{ccl}
+ \toprule
+ Command &A Number & Comments\\
+ \midrule
+ \texttt{{\char'134}author} & 100& Author \\
+ \texttt{{\char'134}table}& 300 & For tables\\
+ \texttt{{\char'134}table*}& 400& For wider tables\\
+ \bottomrule
+ \end{tabular}
+\end{table*}
+
+Always use midrule to separate table header rows from data rows, and
+use it only for this purpose. This enables assistive technologies to
+recognise table headers and support their users in navigating tables
+more easily.
+
+\section{Math Equations}
+You may want to display math equations in three distinct styles:
+inline, numbered or non-numbered display. Each of the three are
+discussed in the next sections.
+
+\subsection{Inline (In-text) Equations}
+A formula that appears in the running text is called an inline or
+in-text formula. It is produced by the \textbf{math} environment,
+which can be invoked with the usual
+\texttt{{\char'134}begin\,\ldots{\char'134}end} construction or with
+the short form \texttt{\$\,\ldots\$}. You can use any of the symbols
+and structures, from $\alpha$ to $\omega$, available in
+\LaTeX~\cite{Lamport:LaTeX}; this section will simply show a few
+examples of in-text equations in context. Notice how this equation:
+\begin{math}
+ \lim_{n\rightarrow \infty}x=0
+\end{math},
+set here in in-line math style, looks slightly different when
+set in display style. (See next section).
+
+\subsection{Display Equations}
+A numbered display equation---one set off by vertical space from the
+text and centered horizontally---is produced by the \textbf{equation}
+environment. An unnumbered display equation is produced by the
+\textbf{displaymath} environment.
+
+Again, in either environment, you can use any of the symbols and
+structures available in \LaTeX\@; this section will just give a couple
+of examples of display equations in context. First, consider the
+equation, shown as an inline equation above:
+\begin{equation}
+ \lim_{n\rightarrow \infty}x=0
+\end{equation}
+Notice how it is formatted somewhat differently in
+the \textbf{displaymath}
+environment. Now, we'll enter an unnumbered equation:
+\begin{displaymath}
+ \sum_{i=0}^{\infty} x + 1
+\end{displaymath}
+and follow it with another numbered equation:
+\begin{equation}
+ \sum_{i=0}^{\infty}x_i=\int_{0}^{\pi+2} f
+\end{equation}
+just to demonstrate \LaTeX's able handling of numbering.
+
+\section{Figures}
+
+The ``\verb|figure|'' environment should be used for figures. One or
+more images can be placed within a figure. If your figure contains
+third-party material, you must clearly identify it as such, as shown
+in the example below.
+\begin{figure}[h]
+ \centering
+ \includegraphics[width=\linewidth]{sample-franklin}
+ \caption{1907 Franklin Model D roadster. Photograph by Harris \&
+ Ewing, Inc. [Public domain], via Wikimedia
+ Commons. (\url{https://goo.gl/VLCRBB}).}
+ \Description{A woman and a girl in white dresses sit in an open car.}
+\end{figure}
+
+Your figures should contain a caption which describes the figure to
+the reader.
+
+Figure captions are placed {\itshape below} the figure.
+
+Every figure should also have a figure description unless it is purely
+decorative. These descriptions convey what’s in the image to someone
+who cannot see it. They are also used by search engine crawlers for
+indexing images, and when images cannot be loaded.
+
+A figure description must be unformatted plain text less than 2000
+characters long (including spaces). {\bfseries Figure descriptions
+ should not repeat the figure caption – their purpose is to capture
+ important information that is not already provided in the caption or
+ the main text of the paper.} For figures that convey important and
+complex new information, a short text description may not be
+adequate. More complex alternative descriptions can be placed in an
+appendix and referenced in a short figure description. For example,
+provide a data table capturing the information in a bar chart, or a
+structured list representing a graph. For additional information
+regarding how best to write figure descriptions and why doing this is
+so important, please see
+\url{https://www.acm.org/publications/taps/describing-figures/}.
+
+\subsection{The ``Teaser Figure''}
+
+A ``teaser figure'' is an image, or set of images in one figure, that
+are placed after all author and affiliation information, and before
+the body of the article, spanning the page. If you wish to have such a
+figure in your article, place the command immediately before the
+\verb|\maketitle| command:
+\begin{verbatim}
+ \begin{teaserfigure}
+ \includegraphics[width=\textwidth]{sampleteaser}
+ \caption{figure caption}
+ \Description{figure description}
+ \end{teaserfigure}
+\end{verbatim}
+
+\section{Citations and Bibliographies}
+
+The use of \BibTeX\ for the preparation and formatting of one's
+references is strongly recommended. Authors' names should be complete
+--- use full first names (``Donald E. Knuth'') not initials
+(``D. E. Knuth'') --- and the salient identifying features of a
+reference should be included: title, year, volume, number, pages,
+article DOI, etc.
+
+The bibliography is included in your source document with these two
+commands, placed just before the \verb|\end{document}| command:
+\begin{verbatim}
+ \bibliographystyle{ACM-Reference-Format}
+ \bibliography{bibfile}
+\end{verbatim}
+where ``\verb|bibfile|'' is the name, without the ``\verb|.bib|''
+suffix, of the \BibTeX\ file.
+
+Citations and references are numbered by default. A small number of
+ACM publications have citations and references formatted in the
+``author year'' style; for these exceptions, please include this
+command in the {\bfseries preamble} (before the command
+``\verb|\begin{document}|'') of your \LaTeX\ source:
+\begin{verbatim}
+ \citestyle{acmauthoryear}
+\end{verbatim}
+
+ Some examples. A paginated journal article \cite{Abril07}, an
+ enumerated journal article \cite{Cohen07}, a reference to an entire
+ issue \cite{JCohen96}, a monograph (whole book) \cite{Kosiur01}, a
+ monograph/whole book in a series (see 2a in spec. document)
+ \cite{Harel79}, a divisible-book such as an anthology or compilation
+ \cite{Editor00} followed by the same example, however we only output
+ the series if the volume number is given \cite{Editor00a} (so
+ Editor00a's series should NOT be present since it has no vol. no.),
+ a chapter in a divisible book \cite{Spector90}, a chapter in a
+ divisible book in a series \cite{Douglass98}, a multi-volume work as
+ book \cite{Knuth97}, a couple of articles in a proceedings (of a
+ conference, symposium, workshop for example) (paginated proceedings
+ article) \cite{Andler79, Hagerup1993}, a proceedings article with
+ all possible elements \cite{Smith10}, an example of an enumerated
+ proceedings article \cite{VanGundy07}, an informally published work
+ \cite{Harel78}, a couple of preprints \cite{Bornmann2019,
+ AnzarootPBM14}, a doctoral dissertation \cite{Clarkson85}, a
+ master's thesis: \cite{anisi03}, an online document / world wide web
+ resource \cite{Thornburg01, Ablamowicz07, Poker06}, a video game
+ (Case 1) \cite{Obama08} and (Case 2) \cite{Novak03} and \cite{Lee05}
+ and (Case 3) a patent \cite{JoeScientist001}, work accepted for
+ publication \cite{rous08}, 'YYYYb'-test for prolific author
+ \cite{SaeediMEJ10} and \cite{SaeediJETC10}. Other cites might
+ contain 'duplicate' DOI and URLs (some SIAM articles)
+ \cite{Kirschmer:2010:AEI:1958016.1958018}. Boris / Barbara Beeton:
+ multi-volume works as books \cite{MR781536} and \cite{MR781537}. A
+ couple of citations with DOIs:
+ \cite{2004:ITE:1009386.1010128,Kirschmer:2010:AEI:1958016.1958018}. Online
+ citations: \cite{TUGInstmem, Thornburg01, CTANacmart}. Artifacts:
+ \cite{R} and \cite{UMassCitations}.
+
+\section{Acknowledgments}
+
+Identification of funding sources and other support, and thanks to
+individuals and groups that assisted in the research and the
+preparation of the work should be included in an acknowledgment
+section, which is placed just before the reference section in your
+document.
+
+This section has a special environment:
+\begin{verbatim}
+ \begin{acks}
+ ...
+ \end{acks}
+\end{verbatim}
+so that the information contained therein can be more easily collected
+during the article metadata extraction phase, and to ensure
+consistency in the spelling of the section heading.
+
+Authors should not prepare this section as a numbered or unnumbered {\verb|\section|}; please use the ``{\verb|acks|}'' environment.
+
+\section{Appendices}
+
+If your work needs an appendix, add it before the
+``\verb|\end{document}|'' command at the conclusion of your source
+document.
+
+Start the appendix with the ``\verb|appendix|'' command:
+\begin{verbatim}
+ \appendix
+\end{verbatim}
+and note that in the appendix, sections are lettered, not
+numbered. This document has two appendices, demonstrating the section
+and subsection identification method.
+
+\section{SIGCHI Extended Abstracts}
+
+The ``\verb|sigchi-a|'' template style (available only in \LaTeX\ and
+not in Word) produces a landscape-orientation formatted article, with
+a wide left margin. Three environments are available for use with the
+``\verb|sigchi-a|'' template style, and produce formatted output in
+the margin:
+\begin{itemize}
+\item {\verb|sidebar|}: Place formatted text in the margin.
+\item {\verb|marginfigure|}: Place a figure in the margin.
+\item {\verb|margintable|}: Place a table in the margin.
+\end{itemize}
+
+%%
+%% The acknowledgments section is defined using the "acks" environment
+%% (and NOT an unnumbered section). This ensures the proper
+%% identification of the section in the article metadata, and the
+%% consistent spelling of the heading.
+\begin{acks}
+To Robert, for the bagels and explaining CMYK and color spaces.
+\end{acks}
+
+%%
+%% The next two lines define the bibliography style to be used, and
+%% the bibliography file.
+\bibliographystyle{ACM-Reference-Format}
+\bibliography{sample-base}
+
+%%
+%% If your work has an appendix, this is the place to put it.
