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.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"154","bibliographic_titles":[{"bibliographic_title":"ゲームプログラミングワークショップ2020論文集"}],"bibliographicPageStart":"147","bibliographicIssueDates":{"bibliographicIssueDate":"2020-11-06","bibliographicIssueDateType":"Issued"},"bibliographicVolumeNumber":"2020"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"created":"2025-01-19T01:09:17.395453+00:00","updated":"2025-01-19T19:05:49.942078+00:00"}
