Hello,
I'm running a genetic algorithm in Matlab with [x,fval]=ga(gaproblem)
This all works fine and I get nice results. Now I wish to plot the best fitness function value at each generation; according to the user manual it should be as simple as setting
gaproblem.PlotFcns=@gaplotbestf;
This however produces no result, I get no figure. As far as I understand @gaplotbestf is built in, and there should be no need to define it, or am I getting it wrong?
It would be nice if someone could help.

PlotFcns needs to be passed in as an option for ga:
problem.options.PlotFcns = @gaplotbestf;
