| Abstract(in English) | This paper proposes an agent oriented model for competitive bidding of a computer bridge. Since bridge auction is a task of imperfect information, each agent has hypothetical reasoning ability and generates hypothetical image of other players' hands by abduction from observation of the bidding sequence. Each agent chooses the next bid according to the criteria: Cooperate with partner to get maximum profit and compete against opponents to minimize the loss. The experimental result shows that our program based on this model can make flexible responses to the wide range of other players' bids and reaches the reasonable contract which maximizes the profit(or minimizes the loss). The importance of preemptive bids to disturb communication of opponents is examined as well as the importance of partnership bidding. |
