|
|
One possible stop criterion for a solution-based heuristic.
|
|
|
|
The stop criterion corresponds to a maximum number of iterations without improvement.

Flag that indicate if there is a maximization (true) or a minimization (false) of the fitness value.
|
|
.PP
|
|
It can be interesting to know this information because some solution-based metaheuristics can generate solutions wiht a fitness that is worse that the best known fitness (in this case, the counter is not reinitialized).
