The Basics of a Reinforcement Learning Pipeline

The board state is essentially what's happening right now. And the history is what was the move before and before and before that. So it might very well be that players who do coordinate, even if they're technically enemies who do coordinate for a mover to are better off at the end than had they not coordinated. In any case, we get the board state as an input and that goes into different directions as you can see.

A team from Meta AI has developed Cicero, an agent that can play the game Diplomacy, in which players have to communicate via chat messages to coordinate and plan into the future.

Abstract:

Despite much progress in training AI systems to imitate human language, building agents that use language to communicate intentionally with humans in interactive environments remains a major challenge. We introduce Cicero, the first AI agent to achieve human-level performance in Diplomacy, a strategy game involving both cooperation and competition that emphasizes natural language negotiation and tactical coordination between seven players. Cicero integrates a language model with planning and reinforcement learning algorithms by inferring players' beliefs and intentions from its conversations and generating dialogue in pursuit of its plans. Across 40 games of an anonymous online Diplomacy league, Cicero achieved more than double the average score of the human players and ranked in the top 10% of participants who played more than one game.
