I've done one (a few in fact). I used it to calculate an 8th-generation
precursor to a particular state in a 64x64 game of life, which as you can
imagine is a fairly intractable problem with 2^4096 possibilities to choose
from! I was running it off and on for nigh on 9 months! But it got pretty
close to an answer.
I made up the code based on a description of the algorithm, and I played
with it rather a lot to try to get it to have the right degree of mutation.
If you're interested, I can try to dig up the code. The main thing I'd say
from a Lingo point of view is: make sure you don't try running it in a tight
loop. Run one generation each frame, and set up a script that saves improved
versions of the genome in an external file. If it's a big problem space then
even a GA may take a good long while!
