In this paper, we tried to make a shogi progam that treats entering-king positions correctly; i.e. selects entering-king moves if possible and defends the opponent's entering-king moves. We have made a couple of experiments to make a entering-king oriented shogi program by means of modifying the evaluation function and the opening book of an open source shogi program Bonanza. We made an evaluation function which has a new feature \"entering-king step\" besides original features, and obtained the weight parameter of this feature by using machine learning.  As a result, we successed to raise the entering-king rate without decreasing winning rate.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"31","bibliographic_titles":[{"bibliographic_title":"ゲームプログラミングワークショップ2011論文集"}],"bibliographicPageStart":"25","bibliographicIssueDates":{"bibliographicIssueDate":"2011-10-28","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"6","bibliographicVolumeNumber":"2011"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"created":"2025-01-18T23:33:38.585661+00:00","id":78250,"links":{}}
