Hi, I am doing some research on feature selection for classfication problem using genetic algorithm in a wrapper approach. 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!) Thanks, Ed
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.

After a little search, I found on CRAN: - gafit: genetic algorithm for curve fitting, - rgenout: R version of genetic optimization using derivatives - subselect: Selecting variable subsets, with function genetic(): genetic algorithm searching for an optimal k-variable subset I don't know if it fits your needs.
