On the Use of Simulated Future Information for Evaluating Game Situations

Abstract

A FOrward Simulation for Situation Evaluation (FOSSE) approach for evaluating game situations is proposed in this paper. FOSSE approach considers multiple future situations to quantitatively evaluate the current game situations. Since future situations are not available during an ongoing game in real time, they are generated by what is called forward simulation. Then the current game situation is evaluated using the future game situations as well as the current situation itself. First, we show the evaluation performance can be increased by using successive situations in time through preliminary experiments. Especially, the effectiveness of using future information rather than using past information is shown. Then, we present FOSSE approach where both the current and the future information of game situations are used to evaluate the current game situation. In the FOSSE approach, the future game situations are generated by forward simulation. Computational experiments are conducted to investigate the effectiveness of the proposed approach.
