MATLAB: Does it show on genetic algorithm plotting ‘gaplotgenealogy not supported for this algorithm’

genetic algorithm

I used @gaplotgenealogy to see if I could find where each new Children comes from (Elite, Crossover, Mutation). But it shows on plotting 'gaplotgenealogy not supported for this algorithm'? I simply coded as opts = optimoptions('ga','PlotFcn',{@gaplotscores,@gaplotgenealogy,@gaplotstopping} Anyone has an idea why it shows words like that?

Best Answer

If you enter

help gaplotgenealogy

you see at the end of the help this statement:

    NOTE: This plot is only available after the GA has stopped and can not
    be used for nonlinear constrained problems.

So, do you have any nonlinear constraints?

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,
