\begin{abstract}
This text is produced from a sample \LaTeX\ file. A copy of the file
can be obtained at the {\tt URL http://www.dsi.unive.it/$\sim$wae97.}
It is designed for the preparation of a camera-ready manuscript for an
article to be included in the booklet of the Workshop on Algorithm
Engineering.
\end{abstract}

\section{Introduction}

To obtain a uniform typesetting style, contributing authors are
required to follow closely the instructions given here.  To avoid
replications in formatting, you must use a style file ({\tt wae.sty})
which contains adaptations of the standard \LaTeX\ {\tt article.sty}
file. In particular, text size, letter size, margins, line spacing
should be kept as in this sample.  Your manuscript must not exceed ten
pages. Final versions ( \LaTeX\ and poscript files for the figures)
must be sent via electronic mail to {\tt wae97@dsi.unive.it} by August
15, 1997. Final versions that arrive late or that deviate from these
guidelines cannot be guaranteed to be included in the workshop
booklet.

\section{General appearance}

This section describes the general structure of an article. Please
avoid ad hoc formatting procedures and try to use as much as possible
\LaTeX\ formatting commands (such as \verb+\section+ and
\verb+\subsection+; itemize, theorem, figure, picture and
thebibliography environments; and so on).
To use the style file {\tt wae.sty}, please start your \LaTeX\ file with the
command:
\begin{verbatim}
\documentstyle{wae}
\end{verbatim}
You may include standard options, but not formatting options (such as
fullpage, 11pt, 12pt, \ldots). If you really feel the urge to include
nonstandard options or your file includes an input command for other
files, please make sure you also send us the appropriate files.

\subsection{Headings}

Use the commands \verb+\section{Section name}+ and
\verb+\subsection{Subsection name}+ to structure your text in
sections and subsections.

\subsection{Lemmas, Propositions, Theorems}

Precise mathematical statements may be organized as is nowadays common in the
mathematical literature by using the ``theorem environments''
\verb+\begin{Thm} ... \end{Thm}+,
\verb+\begin{Prop} ...+ \verb+\end{Prop}+,
\verb+\begin{Lemma} ... \end{Lemma}+,
and so on. These and a few other commonly used environments are
already available in the style file {\tt wae.sty}.

\subsection{Reference to statements}

To refer to a statement, such as a lemma, include a
\verb+\label{your label}+ command in its statement and use
the command \verb+\ref{your label}+. Here is an example:

\begin{Lemma}\label{silly}
If there was enough time to make experiments, then I would have been a
physicist. 
\end{Lemma}

The reference to the example can be done as Lemma~\ref{silly}.

\subsection{Equations}

Equations should be centered and, if needed, should be numbered in the
standard way in \LaTeX. To produce a numbered equation, use the command
\verb+\begin{equation} ...+ \verb+\end{equation}+.
Such numbers are only meaningful if they are used elsewhere in the text.
The mechanism for doing it is the same as for theorems, using the
command \verb+\label{code}+ and \verb+\ref+, except that the latter
should include parentheses: \verb+(\ref{code})+ since equation numbers
should appear in parentheses.

\subsection{Figures}

The text may include figures. These should preferably be produced
within \LaTeX\ itself. If not possible, try to include them in the
form of Encapsulated PostScript files using the documentstyle option
{\tt epsf} and the command \verb+\epsffile{filename}+. (See the manual
for your local implementation of \LaTeX\ for further details.)
Figures are to be embedded in the text near their first reference.
Captions must be set below the figure using the following scheme:
\begin{verbatim}
\begin{figure}
(figure commands)
\caption{your caption for the figure}
\end{figure}
\end{verbatim}
Figure~\ref{fig:ghost} shows an example of including a picture via
{\tt epsfig}.

\begin{figure}
\begin{center}
\leavevmode
\epsfxsize=4cm
\epsfbox{ghost-perim.eps}
\caption{Ghosts getting into perimeters (whatever that means).}
\label{fig:ghost}
\end{center}
\end{figure}

\subsection{Acknowledgements}

Support by grants or institutions should be acknowledged by means of a
footnote produced with the \verb+\footnote{This work was partially...}+
command, included in the appropriate author declaration. Other
acknowledgements should appear at the end of the text, just before the
references, in a special section produced with the command
\verb+\section*{Acknowledgements}+.

\section{Bibliographic references}

References to the bibliography should be cited in the text by a number
enclosed in brackets. This can be done authomatically in \LaTeX\ by
using the command \verb+\bibitem{code}+ to produce the
bibliography entry at the end of the text and the command
\verb+\cite{code}+ to refer to it. The bibliographic entries should be
organized in alphabetical order of the authors' last names. Authors'
names should be given by initials plus last name. Entries should include
title (in italics), name of publication (journal, proceedings), volume
(in boldface), year of publication (in parenthesis for a journal) and
page numbers. Please see below for examples.
Use the following scheme to produce the bibliography:
\begin{verbatim}
\begin{thebibliography}{99}
\bibitem{code} ...
\end{thebibliography}
\end{verbatim}
This is the scheme used by Bibtex. If you use Bibtex, do not forget
to include either the database file or the filename.bib file.
