Hello Again,

Looks like Im getting there now. I did this inside the GA module:

def update(self):

        return self.entities

now Im putting it in my code:

def my_fitness(entity):
        x = ga.update()
        print 'X', x
        fitness = 0.0
        for i in entity:
            if i == 1:
                fitness += 1.0
        return fitness

This fitness fuction sets the evaluation criteria. I does the job, but 
there is a small problem, it returns too much information! for example 
in generation 1 it gives:

X [[0, 0, 1, 1, 0, 1, 1, 1, 1, 0], [1, 0, 1, 0, 0, 1, 1, 0, 1, 1], [0, 
1, 0, 1, 1, 1, 1, 0, 1, 0], [0, 1, 0, 0, 1, 0, 0, 1, 1, 1], [1, 0, 0, 0, 
1, 1, 0, 0, 0, 0]]
X [[0, 0, 1, 1, 0, 1, 1, 1, 1, 0], [1, 0, 1, 0, 0, 1, 1, 0, 1, 1], [0, 
1, 0, 1, 1, 1, 1, 0, 1, 0], [0, 1, 0, 0, 1, 0, 0, 1, 1, 1], [1, 0, 0, 0, 
1, 1, 0, 0, 0, 0]]
X [[0, 0, 1, 1, 0, 1, 1, 1, 1, 0], [1, 0, 1, 0, 0, 1, 1, 0, 1, 1], [0, 
1, 0, 1, 1, 1, 1, 0, 1, 0], [0, 1, 0, 0, 1, 0, 0, 1, 1, 1], [1, 0, 0, 0, 
1, 1, 0, 0, 0, 0]]
X [[0, 0, 1, 1, 0, 1, 1, 1, 1, 0], [1, 0, 1, 0, 0, 1, 1, 0, 1, 1], [0, 
1, 0, 1, 1, 1, 1, 0, 1, 0], [0, 1, 0, 0, 1, 0, 0, 1, 1, 1], [1, 0, 0, 0, 
1, 1, 0, 0, 0, 0]]
X [[0, 0, 1, 1, 0, 1, 1, 1, 1, 0], [1, 0, 1, 0, 0, 1, 1, 0, 1, 1], [0, 
1, 0, 1, 1, 1, 1, 0, 1, 0], [0, 1, 0, 0, 1, 0, 0, 1, 1, 1], [1, 0, 0, 0,

As you can see it is almost the same, the problem is that if I update my 
3D objects with each list, the system becomes too slow because I'm 
working with hundreds and even thousands of generations, and updating 
geometry is not a vera fast process.

The question now would be, how to update my objects only if the new list 
is different from the previous???
