Multi-objective optimization support #37

Closed hongyuanjia closed 4 years ago

hongyuanjia commented 4 years ago

I love how GA package structure the workflow, which is nice and neat. I am trying to adopt GA package in my resent research work. My work mainly focuses on optimizing architecture design options, which involve multi-object optimization (MOO). Currently, does GA support MOO? If not, are there any plans for support it? Thanks!

luca-scr commented 4 years ago

GA package does not support MOO and there is no plan to implement it due to lack of time and interest. When I had to solve a MOO problem I took the strategy to define a fitness function that reduce multiple objective functions into a single (weighted) objective function. It may be simplistic but works reasonably well.

@luca-scr Thanks for the hint. Yeah, whenever it is possible, downgrade the MOO to a mono one is a feasible way. Anyway, thanks for this package!
