(Maybe I should see how this fares before babbling about it, but anyway...)
How this works is: for each attribute, I have an initial weight, a final weight, and a final time (say, 20,000 ticks). The weight shifts linearly from initial to final value until final time, when it stays at final value. Tuning against my 500-bot, 4 season general rumble test bed, I increased my hit percentage from 23.21% to 23.90%. Not sure how much I could've gotten just re-tuning without the shifting, but testing just the initial weights or just the final weights came in around 23.1%. And the previous weights were genetically tuned in a similar fashion, so I think they were close to optimal.
