Portfolio Master Genetic Settings

Could someone give me some more info about how to use this Genetic search.

I have more than 50 profitable EAs and want to generate portfolios. I am not sure what this means:

1. Population size

2. Generations

Also want to find out if there is any way to generate not correlated portfolios. I mean, if i give 50 EAs to generate my portfolios, i want to make sure that portfolio 1 is different to portfolio 2, or i can compare them in some way? Or once i generate one portfolio i should untick all EAs from selected portfolio?

Can someone give me some info a way how to get this done.
