Nice to know that you are improving the GAlib to cope with multiple
objective functions. I don't know the paper you mentioned, but I agree with
Joe Dumoulin's suggestion of incorporating the mutiple objectives into the
representation.  Fuzzy logic might be used to get a single fitness score
from multiple sub fitness scores. Furthermore, fuzzy logic is also something
that simulates biological rules.

I'm implementing the method described by Fonseca and Fleming in their
"Genetic Algorithm for Multiobjective Optimization: Formulation,
Discussion and Generalization"

I think I have to make some changes to GAlib for handling Multiobjective
Optimization Problems,
but I think it is a lot of work. First fo all, I should add a virtual
member function MOGAevaluates into the GAGenome class with its implicit

Do you have any suggestion? 
Has it been done?
