\section{Example}
|
|
|
|
The archive {\tt paradiseo\_practices\_0208.tgz} installed
|
|
on your computer contains a Hill-Climbing implemented using ParadisEO-MO~
|
|
(see {\tt hill\_climbing} in the {\bf build/lesson2} directory).
|
|
|
|
\medskip
|
|
To run it, please go in {\bf build/lesson2} and start the program {\tt hill\_climbing} by giving
|
|
one of the TSP instances located in {\bf tsp/benchs}.
|
|
|
|
|
|
\medskip
|
|
When entering {\tt ./hill\_climbing ../../tsp/benchs/berlin52.tsp}, you should end up with the
|
|
following outputs:
|
|
|
|
\smallskip
|
|

\texttt{87 6 61}\\

|
The printed-out results show for the initial best solution and the final one~:
|
|
\\ \hspace*{0.5cm}-the length of the route
|
|
\\ \hspace*{0.5cm}-the number of cities
|
|
\\ \hspace*{0.5cm}-the route itself (notice that the city index starts from 0).
|
|
|
|
|
|
\section{Tabu search}
|
|
|
|
Study the {\tt hill\_climbing.cpp} file located in the {\bf lesson2} directory
|
|
using~:
|
|
\begin{itemize}
|
|
\item[$\bullet$] the ParadisEO-MO API documentation available at~:
|
|
|
|
\hspace{1cm}http$\,:$//paradiseo.gforge.inria.fr/addon/paradiseo-mo/doc/index.html
|
|
\item[$\bullet$] the source files located in the {\bf tsp/src/} directory
|
|
\end{itemize}
|
|
|
|
\section{Customize the Hill CLimbing}
|
|
|
|
Make a backup (copy) of the cpp file {\tt tabuhill\_climbing.cpp}. You can now modify the
|
|
original {\tt hill\_climbing.cpp} and use the existing makefiles to compile it.
|
|
|
|
Edit and modify the {\tt hill\_climbing.cpp} file~:
|
|
\begin{itemize}
|
|
\item[$\bullet$] Try to tune a few parameters (random seed
|
|
and the move selector) and observe the changes on the final
|
|
solution.
|
|
|
|
\end{itemize}
|
|
|
|
\smallskip
|
|
To compile {\tt hill\_climbing.cpp}, you should use the
|
|
command {\tt make} from {\bf build/lesson2}.
|
|
|
|
\medskip
|
|
Finally, test your modifications on several TSP instances ({\tt berlin52},
|
|
{\tt eil101} ...) and compare the results you get.
