Handling of constraints with single-objective CMAES #150

Closed m-balesdent closed 1 year ago

m-balesdent commented 4 years ago

Hi,

I try to solve contrained single-objective optimization with CMAES and the results I obtain look quite strange.

Regarding line #1235 of algorithms.py, it seems that contraints are not handled in the sort mechanims of cma to select the parents.

"self.population = sorted(self.population, key=lambda x : x.objectives[0])"

Am I wrong? Is there any constraint handling mechanism I missed in the analysis of the code?

Thanks!

Mathieu
