Hi, MATLAB experts.
I'm trying to optimize a problem by using GA(genetic algorythm).
My problem has integer constraints and I want to use mutation, therefore I chosse 'mutationadaptfeasible' as a 'MutaionFcn'.
but Matlab gives me the erorr shown below.
Caution:Problem has integer constraints. The following options will be ignored by GA.
I cannot understand how to solve this erorr.
please tell me genius answer.

The genius answer is given in the documentation of ga:

A way that I usually depend on in such situations is to not specify Integer Constraints (IntCon) but to use round() on those values where I need to use them. This keeps them as integers and GA does a good job to converge accordingly.
And as Stephan mentioned, do go through the documentation.
