Genetic algorithm is not able to find a feasible solution.

I am trying to solve an optimization problem with 200+ opt variables.

I want to use a global solver. It is not possible to define a multi start or global search problem, because every single optimization takes more than 2 days to finish.

I am trying to use matlab genetic algorithm, but it is not able to find a feasible solution (the problem has several non linear constraints). I am using default options.

What can I do?

Thanks

Hi Luigi, Have you tried increasing the initial population size? It usually leads to improved results, I think especially since you're starting from default options.
