Genetic Programming:
is an automated methodology inspired by biological evolution to find
computer programs that best perform a user-defined task.
Genetic Algorithms: search technique used in computer science to find
approximate solutions to optimization and search problems.

Genetic programming usually involves more program-like constructs, such
as Lisp s-expressions.

Python is. However, it is possible to do. Heck, I even had the crazy idea
of doing Genetic Programming in C++ once, however ugly that would've
been!!!!!
Actually, there is an AI project that I'm doing in Python rather than Lisp
because Python is much better supported. A pity, really, since Lisp has so
much more power and expressiveness. Alas, Python has extensive libraries
and are well documented to boot. Only an academic would have the time to do
anything with Lisp. :-(

C++ and it was really ugly at all.

operations on programs you have to support is quite small
(recombination, mutation, duplication, anything else?), and any
advantage LISP has in handling the tree structures is probably not all
that important.
Of course, the big advantage of LISP is the data/code equivalence. In
LISP, you can just eval the programs, whereas in Python you have to
expend quite a bit of effort running them. And that's no small thing.
It's not too bad, though. I've done GP in Python myself, and I it was
pretty straightforward to convert the program trees into expressions
(to be evaled in Python, or compiled and executed in C or Fortran).
But there's really no question that genetic programming is a problem
tailor-made for LISP.

like I need.
Carl Banks wrote about PyODE. I thnk Soya or PySoy is integrating this
soon, so I will be looking into that.
