GA optimization problem, terminate before stall limit

The solution can be seen to be improving but it terminates before the generation or stall limit. Can find a better solution manually by trial and error.

Answer 1

[Alan Weiss]

You can set larger values for various stopping criteria, such as Generations or StallGenLimit. Or you could do yourself a favor and try using patternsearch instead of ga. patternsearch is usually faster and more reliable, and is easier to tune. If you need to start from a wide variety of initial points, and you have finite bounds on all components, try

 x0 = lb + rand(size(lb)).*(ub - lb);
