“Mafia, also known as Werewolf, is a Russian social deduction game created by Dimitry Davidoff in 1986. The game models a conflict between two groups: an informed minority (the mafiosi or the werewolves) and an uninformed majority (the villagers).
At the start of the game, each player is secretly assigned a role affiliated with one of these teams. The game has two alternating phases: first, a night-phase, during which those with night-killing-powers may covertly kill other players, and second, a day-phase, in which all surviving players debate and vote to eliminate a suspect. The game continues until a faction achieves its win-condition; for the village, this usually means eliminating the evil minority, while for the minority, this usually means reaching numerical parity with the village and eliminating any rival evil groups.”
“Werewolf is a subject of artificial intelligence research due to its unique features such as persuasion and deception. The game requires several AI technologies such as multi-agent coordination, intentional reading, and understanding of the theory of mind.
Deep learning has been used in an attempt to develop agents that can win the game as werewolves or as villagers. Regular expressions have been used to parse utterance logs for divulgence (or “coming-out” as a role) and decision information, although one difficulty has been that a statement such as “Player A is a werewolf” could be based on either the player’s ability (e.g. as seer) or just speculation.”
