Title: DipBlue: A Diplomacy Agent with Strategic and Trust Reasoning
Issue Date: 2015
Abstract: Diplomacy is a multi-player strategic and zero-sum board game, free of random factors, and allowing negotiation among players. The majority of existing artificial players (bots) for Diplomacy do not exploit the strategic opportunities enabled by negotiation, instead trying to decide their moves through solution search and the use of complex heuristics. We present DipBlue, an approach to the development of an artificial player that uses negotiation in order to gain advantage over its opponents, through the use of peace treaties, formation of alliances and suggestion of actions to allies. A simple trust assessment approach is used as a means to detect and react to potential betrayals by allied players. DipBlue was built to work with DipGame, a multi-agent systems testbed for Diplomacy, and has been tested with other players of the same platform and variations of itself. Experimental results show that the use of negotiation increases the performance of bots involved in alliances, when full trust is assumed. In the presence of betrayals, being able to perform trust reasoning is an effective approach to reduce their impact.
