[FEATURE] the fitness problem (minimal or maximum?) #97

Closed kunyaoli closed 1 year ago

kunyaoli commented 2 years ago

Dear All：

I have a question about fitness of pygmo, Is there we deal with the multi-problem turn to minimal as default? For example, if I have two objects, one should be maximum, and the other is minimal. So, i should add "-" to my maximum object when I define "pygmo.problem"

Thanks your response.

@kunyaoli yes that is correct.
