Hi Stephen,
I suspect others have done a much better job but I once hacked some
very primitive IDL code that implemented the flow diagram (Fig. 14.1)
describing the genetic algorithm from the book "An Introduction to
Optimization" by Chong and Zak. I tested the modules but never really
did much testing of the overall program as I discovered, in the middle
of writing it, that simulated annealing was much more appropriate for
what I was trying to do. If I can find it, I'll happily give you a copy
of it if you're interested, but with no claims that it does anything
useful or sensible. Since it's a pretty simple algorithm, it's probably
a better exercise to code it up yourself from something like that
flowchart (which was as good as good psuedocode); that way you'd learn
enough about how the algorithm is working, while you're coding.
