Reminds me of what I was working on
I was always tuning bots against DoctorBob to get 100%, and a few ramming bots to get 80%+, however I always find it challenging and tricky. If random path & RHEA based approach can get better than that, I will regard it as the next innovation since 2005 ;)
I would say it is interesting, not necessarily awesome given my bots can't break the top 50 (yet). The main disadvantages right now are the fact that making random but limited population of movement paths means that you don't necessarily ever move using the maximum escape angle, which means it might perform worse vs some statistical targeting just because statistically the movement range is smaller. It does get good results against known targeting methods like circular, hot etc which is comparable to the top traditional surfers.
(As an an aside, the main problem with my bots is predicting the enemy shots, rather than moving around them. This is the same for most surfers I assume, but surfers at least consider lower probabilities. In my method I predict multiple potential bullet positions but don't consider wave danger at other points. I might try changing this as one way to improve it as long as I can find a fast way to evaluate that without breaking the current idea which is to move around the bullets. You can't dodge a full wave so it might just push the bot backwards due to the non-limited move direction)
