[galib] How can I use GAlib244-win to solve multi-objective problem?

[Frédéric Ratle]

It depends on what kind of multi-objective optimization
you want to deal with. If you have a great amount of 
knowledge about the behavior of the objectives, you
can aggregate them in a single-objective function with
a weight vector. If you want to do 'real' multi-objective
optimization, it's another story. Many good algorithms do
exist (NSGA-II, SPEA-II, etc.) but implementing them within
GAlib isn't a piece of cake. The only library I know which has
standard algorithms for multi-objective opt. is actually
the Evolving Objects library, which you can check out for such 
problems. Other libraries do exist, but EO is well-documented.

Frederic
