Lesson 2: Implement a Hill-Climbing using ParadisEO}}

|

\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
|
||||
\noindent
|
||||
\texttt{>> Loading [../../tsp/benchs/eil101.tsp]} \\
|
||||
\texttt{[From] -3435 101 36 55 54 65 50 80 14 27 46 15 93 58 78 47 99 64 68}\\
|
||||
\texttt{49 72 81 82 76 41 16 66 30 29 83 95 71 38 35 19 5 63 26 43 96 79 52}\\
|
||||
\texttt{59 69 7 56 37 3 32 28 9 13 1 91 31 73 11 40 62 17 24 45 88 6 85 22}\\

|
||||
\texttt{[To] -708 101 36 97 91 58 95}\\
|
||||
\texttt{98 92 84 99 90 43 13 37 85 15 60 16 83 4 59 82 44 7 45 35 48 63 10}\\
|
||||
\texttt{18 46 47 81 17 51 26 27 25 39 57 52 100 88 5 93 94 12 1 56 86 96 41}\\
|
||||
\texttt{42 14 40 21 73 71 72 20 3 55 74 22 66 38 24 54 53 23 28 78 2 76 67}\\
|
||||
\texttt{79 11 75 68 0 49 32 80 77 33 50 8 34 70 64 65 19 29 69 31 89 62 9 30}\\
|
||||
\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.
