Genetic Algorithm Limit for more than 300,000 variables #295

Closed SightVanish closed 1 year ago

SightVanish commented 1 year ago

Can GA(Genetic Algorithm) handle a mixed integer(0-1 problem) non-linear optimization problem with 500,000 variables? One objective function: linear; 80 constraints: 78 are linear, 2 are non-linear. The real challenge is the number of variables. I tried to implement that via geatpy but the model cannot return any feasible results. I just wonder whether GA is a good option? Should I seek another non-linear solver?

Hi, actually, it's not a good choice to use GA to address your problem.

Thanks a lot!
