ga and particleswarm has a few stopping conditions I don't want it to stop running once tolerance is met, but continue for max iterations. Tried to do this by setting TolFun to 0 but doesn't work.

options = optimoptions('particleswarm','OutputFcns',@mypsoutputfun, 'MaxIter',MaxGeneration_fun,'SwarmSize',n_pop_ps,'Display','none','StallTimeLimit', 1,'TolFun', 0)

I would suggest an experiment of setting the stall limit fairly high. You could try inf but that might not be accepted. Memory might be allocated for holding this many values so you might not be able to get too wild.

For particle swarm found I have to set 'StallIterLimit' >= MaxIter which effectively guarantees tolerance stopping condition is never reached. Same for StallGenLimit in GA.
