The problem exists in estimating the status of the game phases. It is said that there are three phases in the Shogi. They are called; opening, middle phase, and endgame. The importance of each shogi piece changes depending on the current phase. The problem lies in how to select the appropreate strategy in each phase. At present, Computer Shogi programs are not good at estimating the phase, while professional Shogi players are. In this paper, we introduce the Dempster-Shafer theory to handle with the uncertainty in professional Shogi players. We also introduce three uncertain measures to estimate the phase of the game. Using the game record in 2001 and 2002, these measures are calculated to show the feasibility of our approach.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"43","bibliographic_titles":[{"bibliographic_title":"ゲームプログラミングワークショップ2003論文集"}],"bibliographicPageStart":"39","bibliographicIssueDates":{"bibliographicIssueDate":"2003-11-07","bibliographicIssueDateType":"Issued"},"bibliographicVolumeNumber":"2003"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-18T23:44:01.537355+00:00","id":97539,"links":{}}
