Behavior Observation-Based Rival´s Private Information Inferring

It is important for having the initiative in competition to infer the rival´s private information accurately. In this paper, the rival´s decision-making model is described by influence diagrams. According to the criterion that rival is apt to gain the maximum expected utility in whole multi-steps decision rather than gain the maximum expected utility just in each of the decision steps, we infer rival´s private information about cost and bankroll through observing rival´s decision behaviors and using the Genetic Algorithm (GA). The experiment results show that our proposed method is both accurate and reasonable.
