Construction of a cooperative partner system of Imperfect information game

Abstract

This paper aims at the construction of a cooperative partner system that plays a seven-card stud poker game with a human partner against a computer opponent player. At each situation, the partner system gives a presentation to a human player about which action to take the game and the grounds for that action. If a human player makes another action, a human player and the partner system discuss which action to take by presenting their grounds for the action to each other as follows. (1) A human player selects the grounds for his/her action. (2) If the partner system accepts the player's grounds, they take the action which a player chooses, Otherwise, the partner system asks whether the player has other grounds or not. Through discussion, a human player and the partner system play a poker game cooperating with each other This paper also performs comparative experiments to confirm the usefulness of the presented partner system. In the experiments each subject plays games with/without the partner system.
