To my knowledge, two packages have an implementation of an evolutionary, or genentic, algorithm. Gafit is a curve fitting package and rgenoud for function minimisation (combined with, iirc, a derivative-based Quasi-Newton approach for unconstrained problems). One thing, in the S-Plus robust library, the robust regression package lmRob has an option to use a genetic algorithm in the resampling scheme to obtain initial S-estimates.

I am wondering if there is some package which is already built for this purpose. I was advised before about dprep package but I don't think it used GA there (if I am wrong, please correct me!)
