\section{Instructions for running the data generating program Graphs1}
The folder GraphsGeneration contains the following files:
\begin{enumerate}
\item Graphs1.java java program source code.
\item Graphs1.class the compiled class file.
\item Tools.class methods used in Graphs1.java
\item compile.bat  a batch file that will compile Graphs1.java
\item run.bat a batch file that will run Graphs1.class
\item Sample1.txt an example of a simple graph generated by Graphs1
\item weighted an example of a weighted graph generated by Graph1.
\end{enumerate}
{\bf Assumptions:} you have the latest JDK (Java development Kit) installed in your computer in the default directry created by the Java installer.
\subsection{  Running the program.}
\begin{enumerate}
\item Double click on the icon run.
\item You will be presented with five options:
\begin{itemize}
\item [a.] G-generate a simple graph.
\item [b.] D- generate a directed graph.
\item [c.] W-generate a weighted graph.
\item [d.] A-generate an assignment problem.
\item [e.] T-generate a TSP instance.
\end{itemize}
\item Make your selection.
\item Enter the size 
\item Enter density, the percentage of edges that will be added. For instance, entering 5 will generate an object with about $0.5$ of the possible edges. Entering 3 will generate about $0.3$ of the deges.
\item Enter name of file:  like myexample.txt. Do not forget the file extension that will determine which application can view the file. I use .txt.
\item Select a directory. Either put a complete path such as c:myprograms or just enter . (period) if you want the file to be generated in the same directory as the program.
\end{enumerate}
