"Hearty" is a complete rewrite of the "framework" (if you want to call it that) which was used by Robo and Mabel. It uses Mojave's port of the Battlesnake rules to generate future game states. The alpha-beta pruning Minimax algorithm has been updated to predict moves for multiple snakes. The floodfill algorithm has received many bugfixes. The board scoring heuristic takes many more factors into consideration. And this snake features a full regression test suite. Hearty currently outperforms my old snakes in all game modes except Constrictor. It gets its' name because it runs on the Heart web server (giving 2x faster response times than OpenResty, which was used by my previous snakes). Written in Lua, running in Docker and hosted by Fly.io.
