This paper presents an efficient deletion method for MP double-array. The method dynamically removes keys from MP double-array without increasing empty elements. From experimental results for the key set which consists of 100,000 keys, it turned out that the presented method is about 17窶骭€460 times faster than the conventional method and maintains high space efficiency.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1902","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"1894","bibliographicIssueDates":{"bibliographicIssueDate":"2006-06-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"6","bibliographicVolumeNumber":"47"}]},"relation_version_is_last":true,"item_2_alternative_title_2":{"attribute_name":"その他タイトル","attribute_value_mlt":[{"subitem_alternative_title":"情報検索"}]},"weko_creator_id":"1"},"created":"2025-01-18T22:45:13.926362+00:00","id":10277,"links":{}}
