Dear all, Is there any generic algorithm code for optimization implemented in R? I searched without success. Thanks, -- Zhu Wang Statistical Science Department Southern Methodist University Phone: (214)768-2453 Fax: (214)768-4035 Email: zhuw at mail.smu.edu

Sorry, it is my bad.
I mean genetic algorithm. It seems genoud {rgenoud} is the one I am
looking for.

Are you sure? look at "nlm" on base pkg and at pkgs "nls" "nlme" ... all pkgs to minimize something optimize or better, what signify optimize for you?

Hi. Here is GA. I've never used this. http://www.dst.unive.it/~claudio/R/index.html#ga But this can deal with GP(genetic programming)? Cheers.
Could it be that you meant genetic (rather than "generic") algorithm? If so, from the package descriptions, the "gafit" and "seao" packages on CRAN might be relevant.
