Maximizing flow as a metacontrol in Angband

Abstract

Flow is a psychological state that is reported to improve people's performance. Flow can emerge when the person's skills and the challenges of their activity match. This paper applies this concept to artificial intelligence agents. We equip a decision-making agent with a metacontrol policy that guides the agent to activities where the agent's skills match the activity difficulty. Consequently, we expect the agent's performance to improve. We implement and evaluate this approach in the role-playing game of Angband.
