[galib] Re: Obtain "bestIndividual()" value

[Luca Moscatelli]

Thanks,
   But, with some help, I used another (and better, I suppose) solution.

Here to you:
First of all, you put the best individual into an appropriate genome
(GARealGenome in my case):

GARealGenome best = (GARealGenome &)ga.statistics().bestIndividual();

Then
float f = best.gene(n);
where 'n' is the value into the gene you are interested in...

I tried this approach and it works!
Bye,
Luca
