Re: How to handle constraints?

Carlos A.Coello wrote a quite comprehensive review/survey different
constraint handling approaches. do osme google work you will find it.

title is "Theoretical and numerical constraint-handling techniques used with
evolutionary algorithms: a survey of the state of the art"

good luck.
