Hi everyone, My problem is: I have two objective functions and I want to set the stopping criteria is when the two objective functions (both of them) reach the value of zero ("0"). Could someone please guide me how can I do it or help me with some clues for this. I read the Stopping Criteria in matlab here https://www.mathworks.com/help/gads/genetic-algorithm-options.html#f8335 but I didn't find the way for my situation. I appreciate your help. Thank you!

在 MATLAB Online 中打开

I am not at all sure that I understand what you are trying to do, but it is possible that an Output Function could stop your optimization when you like.

However, it is also not clear to me that you have formulated your problem properly as a multiobjective problem. Is it the case that a single objective for your problem could be

fun = abs(f1(x)) + abs(f2(x))

where f1 and f2 are the two objective functions?
