In general, a player at the lowest place should select a strategy that can obtain higher scores, while a player at the first place should select another strategy to win faster than the other players. This paper proposes a new method for single-player mahjong,that can change the strategy by changing the value of one parameter. It is based on the Monte-Carlo method proposed by Komatsu et al, and it uses two metrics as a reward in playouts, one for getting higher scores, and the other for winning faster. We compare our method with others by performing computational experiments.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"178","bibliographic_titles":[{"bibliographic_title":"ゲームプログラミングワークショップ2015論文集"}],"bibliographicPageStart":"172","bibliographicIssueDates":{"bibliographicIssueDate":"2015-10-30","bibliographicIssueDateType":"Issued"},"bibliographicVolumeNumber":"2015"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":145803,"updated":"2025-01-20T18:13:58.511449+00:00","links":{},"created":"2025-01-19T00:21:23.357433+00:00"}
