\subsection{Detailed Description}
\subsubsection*{template$<$class M$>$ class moRandImprSelect$<$ M $>$}

One of the possible \doxyref{moMove}{p.}{classmo_move} selector (\doxyref{moMoveSelect}{p.}{classmo_move_select}). 

All the neighbors are considered. One of them that enables an improvment of the objective function is choosen.

if a move give a better fitness than the initial fitness, it is saved and the fitness too.

\item[Parameters:]
\begin{description}
\item[{\em \_\-move}]a new move. \item[{\em \_\-fitness}]a new fitness associated to the new move. \end{description}

The move selection. 

One the saved move is randomly chosen.

\begin{Desc}
\item[Parameters:]
\begin{description}
\item[{\em \_\-move}]the reference of the move that can be initialised by the function. \item[{\em \_\-fitness}]the reference of the fitness that can be initialised by the function. \end{description}
