ga output more solutions
显示 更早的评论
Dear All,
I am using optimtool(ga) to optimize a function and I am wondering if there is an option to output not only the best solution (lowest fitness) but more than one with the lowest fitness.
Thanks, Chris

You can report the fitness values at any number of points that GA examined by using an output function.

I think the question is about how to find additional locations at which the solution is also the minima... but I am not sure of that interpretation.
Depending on the shape of the function, it could be the case that while evaluating it will happen to find multiple locations that match the same minima (if the valleys are "close" together.) Or with other functions, the minima might be some distance apart, in which case it might be a matter of restarting the entire ga() with different initial random locations.
