Dynamic Reweighting

For tuning weights in a gun, I'd strongly recommend testing things offline with WaveSim or similar. It's a couple orders of magnitude faster to test against pre-gathered data.

Also, I've done quite a bit of tuning of gun weights this way. The gun weights in Diamond were evolved through a genetic algorithm with WaveSim. But honestly it barely outperforms the hand-tuned weights I had before that. I'm fairly skeptical that it's worth ever straying from "generally optimal" in order to eventually get "bot-specific optimal". That is, I think a gun with generally optimal weights tuned over 10,000 matches will beat bot-specific optimal tuned over <= 35 rounds.

Worth noting that all the tuning I've done was specifically on attribute weights though, not decay rate or other factors. My main gun doesn't decay, just my Anti-Surfer gun. (And you may not want to tune an AS gun against pre-gathered data, though Skilgannon has.)
