Fitness proportionate / roulette-wheel selection, when initial
> How do you calculate the fitness value for each member? I'm trying to find parameters for a second order damping response. I have my F = [ 0 1 ; - w^2 -2*w*z] c = [1 0]; and my system is sys = ss[F, [], c, []); because there are not external inputs and I set an initial value for x0. So I calculate the outp... 17 Feb 2010 02:14
