However, it is not necessarily true in practice. In this paper, we pursue a method that automatically suggests an efficient algorithm for user's source code when such an algorithm is available.

Suggesting an efficient source code that can be adapted to user's source code easily. In this paper, we formulate this problem as a binary classification problem of the efficiency and tackle it with a machine learning method based on submitted source code on an online judge system.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告ソフトウェア工学（SE）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2019-02-28","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"10","bibliographicVolumeNumber":"2019-SE-201"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"created":"2025-01-19T00:59:53.898270+00:00","updated":"2025-01-19T23:18:18.862795+00:00"}
