The tournament models natural selection, but no changes and therefore evolution occurs.

Idea: everyone has access to a constant 'm', which they can use in their bot's code however they like. m is set by the botwriter's initial conditions, then when a bot has offspring in the natural selection tournament, one-third of the offspring have their m incremented by 1, one-third have theirs decremented by 1, and one third has their m remain the same. In this manner, you may plug m into any formulas you want to mutate over time.

Excellent.

Perhaps m could serve as a 'location', so that you'd be more likely to meet opponents with similar m values to your own.
