Selection function in genetic algorithm
显示 更早的评论
When i specify integer constraint in genetic algorithm a warning which says:
Warning: Problem has integer constraints. The following options will be ignored by GA:
SelectionFcn
so my question is, what selection operator genetic algorithm uses when we specify constraint to be integer constraint?

Hi,
the SelectionFcn ga uses, will be the binary tournament selection function. All other settings are being overrided when you include integer constraints.

Hi,
standard is a tournament size of 4. But in your case the Tournament Size is 2, due to the use of the penalty function used by ga when working with integer constraints:
.
.
which is described below:
