\section{Introduction}\label{sec:1}
{\bf Pesquisa Operacional} publishes theoretical and applied papers
of any {\bf OR} sub-areas, as well as surveys on topics of interest
and papers on the history or methodology of {\bf OR}. Submitted
papers must be written in English, must be original, and must not
have been accepted for publication (or published) by a refereed
journal, nor be in the process of evaluation for publication by
any other periodical. In addition to originality and relevance,
it will be taken into account the quality of presentation (clarity,
style and organization of the text) and the adequacy of the text
to the interests of the readers of the journal. Submitted papers
will be evaluated by at least two referees using a double blind
review system and the final decision will be communicated to the
corresponding author by the Editor-in-Chief.
This is time for all good men to come to the aid of their party!
Sample: Let $\phi_{t}$ be an Anosmia flow on a compact space $V$
and $A \subset V$ a dense set. Say that the upper Lacunae
exponents are \emph{$\frac{1}{2}$-pinched} on $A$ if
\begin{equation}\label{eq:11}
(a+b)^2 = a^2 + 2ab + b^2
\end{equation}
and so we have solved equation \ref{eq:11}.
An unique figure can be inserted using the following example.
\begin{figure}[!htb]
\centering
\includegraphics[scale=1.2]{fig1.eps}
%ou \includegraphics[scale=1.2]{fig1} caso a imagem esteja em png, jpeg, etc
\caption{Place text here with your desired caption.}\label{fig:1}
\end{figure}
Figure \ref{fig:1} shows a photograph of a gull.
Figures side by side can be placed as follows.
\begin{figure}[!htb]
\centering
\subfloat[Figure at left]{
\includegraphics[scale=0.3]{fig1}\label{fig4}
}\qquad
\subfloat[Figure at right]{
\includegraphics[scale=0.3]{fig1}\label{fig3}
}
\caption{Figures side by side}
\end{figure}
Figure \ref{fig4} is at left and Figure \ref{fig3} is at right.
An environment tabularx, an extension of tabular, creates a paragraph-like column whose width automatically expands so that the declared width of the environment is filled. Table \ref{table:tab1} shows a minimal working example.
\newcolumntype{C}{>{\centering\arraybackslash}X}
\begin{table}[!htb]

\caption{Insert caption here.}
\begin{tabularx}{1.0\textwidth}{ C | C | C | C }
\toprule

\midrule

\section{Previous work}\label{sec:2}
A simple \LaTeX{} example of one author was written by \citet{moretti2003weighted}
and several authors by \citet{bechara1986use}.
A book can be cited by \citet{kleinrock1975queueing}.
A much longer \LaTeX{} example was written by \citet{maculan2003integer}
An example of technical report was written by \citet{HoracioYanasse}.
