Erastus is an AI engine for playing the board game Santorini. You can play against it online at https://erastus-ai.fly.dev. You may want to learn the rules first (Erastus only plays the basic game).
Erastus uses a Monte Carlo tree search algorithm that gets stronger as it runs more iterations. The Fly instance linked above is capped at 40K iterations, but experimentation shows that playing strength improves up to around 200K iterations. Parallel searches can also be ran simultaneously across different workers to further increase strength. The Fly instance is capped to 1 worker, but experimentation suggests that strength improves up to at least 8 workers.
An easy way to run your own instance is to use Docker
Compose and the provided docker-compose.yml
file. The app will be accessible at http://127.0.0.1:9000.
