I believe that the CS term for these possibilities are genetic programming
(which might or might not be used for genetic algorithms). Genetic
algorithms are quite common (although that term might not be used), and is
often seen as an AI technique. Genetic programming is probably not that
common, partially because it is not very obvious how it should be used;
What decides how sucessful a program is without it turning into an
algorithm itself? I know one company that say they use genetic programming
to find search queries (in a form of query language) for biological (DNA
searches and such) research, and then in an interactive environment where a
researcher can tune the generational environment while looking at the
search results unfold.

Definately very interesting :)
