MATLAB: Customizing fitness function of genetic algorithm

fitness functiongenetic algorithm

HI, all

I am trying to implement a Genetic algorithm through matlab. Is there any code that I can customize the fitness function of GA?

I wonder if I have to implement it from scratch, or if there is a package that is easy to use.

MATLAB: Genetic Algorithm fitness value

As stated in the documentation, GA attempts to find a minimum of the fitness function.

As stated in the documentation, best fitness means the lowest fitness function among all members in the population. Mean fitness is the average over all members in the current population. If you have the same value for best and mean, then your population has little diversity, or your fitness function returns the same value for all members of the population.

Good luck,
