[galib] Best Genomes

[Παναγιώτης Παναγή]

Write a terminate function and inside store the best genomes of each
generation, something like this:

GABoolean GATerminateUpponGeneration(GAGeneticAlgorithm& ga){
	string s;
	//output best genomes of each generation
	s=(string)ImageNumber+"\\";
	s+="FitnessBestGenomes.txt";
	ofstream qout(s.c_str(),ios::app);
	qout<<"Current generation is: "<< ga.generation()<<'\n';
	qout<<"Rank\t\tFitness"<<"\n----\t\t-------\n";
	for (int i=0;i<10;i++){
		qout<<i+1<<"\t\t"<<ga.statistics().bestIndividual(i).score()<<'\n';
	}
	qout<<"\n\n";
	deviation=ga.statistics().current(GAStatistics::Deviation);
	return(ga.generation() < ga.nGenerations()  ? gaFalse : gaTrue);
}

You can set the number of best genomes to keep with this:
ga.nBestGenomes(nbestgen);
So in this example nbestgen is 10
