Yep, but GP and GA are somewhat different. GP is a way of evolving
LISP programs, that doesn't use mutation in the same way that GA does,
and uses specialized operators to crossover LISP S-expressions.

@Book{Davis91,
  author =       "Lawrence Davis",
  title =        "Handbook of Genetic Algorithms",
  publisher =    "Van Nostrand Reinhold",
  year =         "1991",
  address =      "New York",
}

    bleydorf> Breeder definately contains genetic "stuff"...

Yep, but it cannot be used to evolve LISP, or any other kind of
programs, since it's chromosomes are binary strings, and not LISP
expressions.

As for using genetic programming in Swarm, it would probably be a
matter of embedding a LISP interpreter into it. I don't know if it's
really worth the while, most of the stuff that can be done with GP can
be done with GA too. There is already an interpreter embedded in
Swarm, tcl interpreter, but I doubt somebody has tried to make tcl
programs evolve. What makes LISP S-expressions evolvable is (found in
page 71 of Koza's "Genetic programming") probably makes tcl evolvable
too. Most of the seven reasons Koza offers for LISP are check out for
tcl too. Well, just a thought.

PS: Just did a GA in JavaScript, in case somebody is interested: check
it out at http://kal-el.ugr.es/~jmerelo/GAJS.html.
