This is a Battlesnake that I made a a while ago, which I still run on fly.io to this day. Occasionally, I may try to improve it, although I have a few other things going on right now, so it’s not top priority.
Currently, it uses a heuristic approach combined with a Monte-Carlo tree search. However, that lead to worse performance both in time and in ability, so my next steps are to either roll it back to plain heuristics or to improve upon the search.
