Dear all,

I am struggling with finding the arg max of a function f(x) using 'ga'. As ga only minimises functions, I need to multiply it by -1 -> g(x)=-1*f(x) to change it into a minimisation problem. However, I would like to plot best, worst and mean scores and values of the original function. Both "gaplotrange" and "gaplotbestf" show the values also multiplied by -1 (values of g(x)). Is there a way to bypass that and display the values of the original function f(x) being maximised ?

Br,

Mariusz
