I'm presently doing research on Genetic Programming. I'm just an undergrad but I've read a fair amount on the subject and feel that I basically understand it at this point. However my understanding is largely academic and I'm curious as to how marketable the ideas are. Since YC is exactly the crowd that I should ask to find this out, I'm asking. Particularly has anyone used any sort of an evolutionary solution in their product, considered it? If the later why did you decide against it? Has anyone heard of it or is it a new idea? Most important question, who's intrigued and sees potential? Because I do.
