Quoting from aiwolf.org:
a project to create an “Artificial Intelligence Werewolf” (AIWolf) to play as the werewolf in place of a human player. The objective of this comprehensive project is not only to develop a game-playing algorithm, but also to develop virtual agents, real robots, and so on.
The AI Competition currently has 2 branches, one protocol-based where agents can use a predefined grammar to communicate, and one NLP-based. This repository has information on the protocol-based branch of the competition.
To learn the rules and how to play the Werewolf game, please refer to this website
See the docs/ directory for the original documentation of AIWolf, manual/ for information about how to setup your own agents and run them, and src/ for sample agents.
