As the first step to that end, we will explore a method to improve the efficiency of reinforcement learning by using a simplified mahjong game, Suzume-Jong. Suzume-Jong is a game that reduces the number of hand tiles and tile types from ordinary mahjong and has a simplified rule. When performing reinforcement learning of a multiplayer game, it is necessary to prepare another player as an environment like the reinforcement learning of a single agent. In this research, as opponent players, we used a Suzume-jong player that selects a move that maximizes the expected value of the sum of the discounted rewards taking only his tiles into account. As a result, we succeeded in creating a player of comparable strength to the opponent’s players. Next, we tried to use the predicted value by Global Reward Prediction proposed by Super Phoenix as a reward, aiming to minimize the average ranking. However, we have not achieved the improvement of the average ranking.}, pages = {147--154}, publisher = {情報処理学会}, title = {深層強化学習を用いた麻雀プレイヤの構築}, volume = {2020}, year = {2020} }
