\section*{Introduction}

The proceedings are typed in the \LaTeX system in UTF8 encoding.

{\bf It is necessary for authors to use this template in\LaTeX according to this sample file and conference styles} \verb|oss-conf.cls| (Slovak version) or \verb|oss-conf-eng.cls| (English version).
The files are stored on the website \url{http://ossconf.fri.uniza.sk}.

\bigskip

Please do not use this command \verb|\bigskip|.
The command is there only for paragraph clarity.
Separate paragraphs only with empty lines.

\bigskip

Please draw images using \LaTeX{} packages or insert {\sc JPG}, or {\sc PDF} and {\sc PNG} files.
Please publish screenshots and photographs in such a resolution that they are readable in the printed version of the B5 format.

\bigskip

Do not use non-standard fonts in the \LaTeX{} format (e.g. \verb|libertinus|), they will be replaced with standard fonts to match the concept of the proceedings.
{\bf If you use non-standard packages, they must correspond to the style of this proceedings and must be attached.}

\bigskip

The author(s) will send the source file in the \LaTeX{} format (including all used images and files!) with the attached (corresponding) PDF file to the conference or editorial board's e-mail address.

\bigskip

{\bf A contribution to the printed version of the proceedings must have an even number of pages (max. 10)!}
The number of pages in the online version of the proceedings is not limited. In the online version, the mutation of the contribution may be extended compared to the printed version.

\bigskip

Each of the proceedings (printed and online versions) has a separate ISBN.

\bigskip

The contribution includes abstracts
and lists of keywords in English and Slovak/Czech (also in the Slovak/Czech version of the contribution).
The author's address, or all authors separately, also includes contact addresses (mostly work) and e-mail addresses, which will be published in the proceedings.
All contributions are peer-reviewed.

\subsection*{Including {\sc JPG}, {\sc PDF} or {\sc PNG} pictures}

To include the pictures (in print, they will be shown in grayscale only) use package \verb|graphicx| (see Figure~\ref{picture1} or Figures~\ref{picture2}, \ref{picture3}).
To create pictures you can use enviromment \verb|picture| or packages \verb|TikZ|, \verb|PSTricks|, \verb|Asymptote|.


{\footnotesize
\begin{verbatim}
  \begin{figure}[ht]
  \centering
  \includegraphics[width=.9\linewidth]{pict01.pdf}

\begin{figure}[ht]
  \centering
  \includegraphics[width=.9\linewidth]{pict01.pdf}
  \caption{Picture 1 ({\sc PDF} file)}

For two or more ones pictures:

\begin{verbatim}
  \begin{figure}[ht]
  \begin{minipage}[t]{.5\linewidth}

In the article~\cite{blasko} or \cite{rybicka} authors expressed several interesting opinions \dots

You can include tables online in the text (see~\cite{blasko2}) or as a separate ``Table'' objects (Table~\ref{tab001}), see the source below. 


\begin{verbatim}
You can include tables online in the text (see~\cite{blasko2}):

or as a separate ``Table'' objects (table~\ref{tab001}):

\section{Measurements}

In the list environments \verb|itemize| (first example) and \verb|enumerate|
you can use the optional parameters for item styles.
This is the \verb|itemize| environment:


\begin{itemize}
       
\item
we can process the data, if the amount of experiments is not huge,

\item[(b)] 
we can process the data, if the amount of experiments is not huge,

\item[(e)] 
we can process the data, if the amount of experiments is not huge.
\end{itemize}

And the same with \verb|enumerate|:

\begin{enumerate}

\item
we can process the data, if the amount of experiments is not huge,

\item
we can process the data, if the amount of experiments is not huge,

\item[(e)] 
we can process the data, if the amount of experiments is not huge.

\end{enumerate}


\section{Typesetting the Source Codes}

For program listing presentations, you can use the \verb|\verbatim| environment, i.e.
\nopagebreak[4]

\medskip

\noindent
\verb|{\footnotesize|                                \\
\verb|\begin{verbatim}|                              \\
\verb|    procedure FLOYD(${\mathrm A}$)|            \\
\verb|      ${\mathrm D} = {\mathrm A}$|             \\
\verb|      for $k \in N$ do |                       \\
\verb|        for $i \in N$ do |                     \\
\verb|          for $j \in N$ do|                    \\
\verb|            if $d_{ij} > d_{ik}+d_{kj}$ then|  \\
\verb|               $d_{ij} = d_{ik}+d_{kj}$|       \\
\verb|    $\text{return}~{\mathrm D}$|               \\
\verb|\end{verbatim}}|

\medskip

\noindent
The result is as follows:

{\footnotesize
\begin{verbatim}
  procedure FLOYD(${\mathrm A}$)
    ${\mathrm D} = {\mathrm A}$
    for $k \in N$ do 
      for $i \in N$ do 
        for $j \in N$ do
          if $d_{ij} > d_{ik}+d_{kj}$ then
             $d_{ij} = d_{ik}+d_{kj}$
  $\text{return}~{\mathrm D}$
\end{verbatim}}


Or you can also use the \verb|listings| package:

\begin{verbatim}
{\footnotesize
\begin{lstlisting}[mathescape]{}
  procedure FLOYD(${\mathrm A}$)
    ${\mathrm D} = {\mathrm A}$
    for $k \in N$ do 
      for $i \in N$ do 
        for $j \in N$ do
          if $d_{ij} > d_{ik}+d_{kj}$ then
             $d_{ij} = d_{ik}+d_{kj}$
  $\text{return}~{\mathrm D}$
  \end{lstlisting}}
\end{verbatim}


{\footnotesize
\begin{lstlisting}[mathescape]{}
procedure FLOYD(${\mathrm A}$)
  ${\mathrm D} = {\mathrm A}$
  for $k \in N$ do 
    for $i \in N$ do 
      for $j \in N$ do
        if $d_{ij} > d_{ik}+d_{kj}$ then
           $d_{ij} = d_{ik}+d_{kj}$
$\text{return}~{\mathrm D}$
\end{lstlisting}}



Or other example:

\begin{verbatim}
\lstset{%
language={[Sharp]C},
breaklines=true,
breakindent=0pt,
tabsize=2,
showstringspaces=true
}
%
{\footnotesize
\begin{lstlisting}
  using System;
  public class Foo
  {
   public static void Main()
   {
       Console.WriteLine("I Love LaTeX");//This is a~comment.
   }
   /*This is a~comment too.*/
  }
\end{lstlisting}}
\end{verbatim}



\lstset{%
language={[Sharp]C},
breaklines=true,
breakindent=0pt,
tabsize=2,
showstringspaces=true
}
%
{\footnotesize
\begin{lstlisting}
using System;
public class Foo
{
 public static void Main()
 {
     Console.WriteLine("I Love LaTeX");//This is a~comment.
 }
 /*This is a~comment too.*/
}
\end{lstlisting}}
