However, we raise a question that there is a strong correlation between total energy consumption of a program and duration of its execution. If this hypothesis is correct, the problem of reducing energy consumption can be solved by shortening the duration. In this paper, we investigate the relation between total energy consumption and duration about different sorting algorithms and Java Collections classes. Experimental results reveal that there is a strong positive correlation between them. We also find that measured metrics have large impacts on program's energy consumption in the order of its duration and mean energy consumption per unit of time. As a result, we conclude that adopting an implementation with short execution time makes whole program energy-saving.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1272","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"1262","bibliographicIssueDates":{"bibliographicIssueDate":"2018-04-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"4","bibliographicVolumeNumber":"59"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-19T00:54:05.215580+00:00","id":187409,"links":{}}
