Can anyone provide some pseudo code for a roulette selection function? How would I implement this:
I don't really understand how to read this math notation. I never took any probability or statistics.
It's been a few years since i've done this myself, however the following pseudo code was found easily enough on google.
for all members of population sum += fitness of this individual end for for all members of population probability = sum of probabilities + (fitness / sum) sum of probabilities += probability end for loop until new population is full do this twice number = Random between 0 and 1 for all members of population if number > probability but less than next probability then you have been selected end for end create offspring end loop
The site where this came from can be found here if you need further details.
