Hi,
nice work!
One thing, though: You wrote in the code description that you've not seen a GA that encodes mutation rate in its genome. It has been some years since I've studied the theory of GAs, but the idea to include mutation rate into the genome is quite old actually, and has been investigated thoroughly. My memory is a bit fuzzy about it, but I seem to remember that it's no advantage to do so; it doesn't speed up the GA converging in any way, and only makes it more complicated. But then it doesn't slow it down much either as far as I remember, so...
I can't give you the exact details, but that should be easy to find in the literature. If you're really interested, I could try to find the relevant papers again.
