"Evolution" is a touchy word, because there are so many idiots who will deny it exists or who will distort it horribly.

It's a shame that a useful word is less useful now - purists want to make sure that biological evolution is never misrepresented. That's fair enough. It's a simple concept and lots of people (even the ones who accept evolution) sometimes make mistakes.

Personally, I think the term "computational evolution" is clear enough.
