Multiobjective genetic algorithm stopping criteria

Hi,

I want to optimize an objective function which returns 3 values [y(1), y(2), y(3)] using gamultiobj toolbox. I set up the code and the simulation runned fine. However, I could not find a way to set a stopping criteria such as : y(1) < -10, y(2) < -5, y(3) < -60, because the fitness limit only takes scalar values. Do you know how to overcome this problem and make the simulation stops if all three conditions are satisfied ? Something like

options = gaoptimset;
options.FitnessLimit = [-10; -5; -60];

Thank you!

You can stop gamultiobj at any point using an output function. To stop the iterations, set state.StopFlag to a nonempty string.
