Hi all,,
i know that doc 'ga' tell me about Find minimum of function using genetic algorithm. How to find max fuction using genetic algorithm?
thanks..

While you find a lot of tools to minimize a function F, you find no functions to maximize F. Fortunately you can minimize G = -F, such that you do not need to program your own maximization tool.

hello to all,
I am trying to solve an optimization problem to find maximum value of my fitness function that calculate rate. My fitness function for each individual return the value for 1/rate , as GA solver minimizes so I used 1/rate to maximize rate. once the GA solver executes and return the minimum value, then I used to take another inverse to get the actual maximized value for the rate. Is the procedure is correct? As also you people suggested to include a (-) negative sign in front of the function in the objective function code. i didnot understand the actuall way to do it. Shall i have to take negative of fun (-fun) when calling it in ga solver below?
suggest me how to perform maximizing optimization problem with GA solver.
Thanks in advance

I have
f = fitnessfunction(h)
I tried placing a negative sign infront of the function but it did not work.
