Since MOGAs require a special selection mechanism such as ranking strategy and niching method to preserve diversity of individuals, MOGAs require larger computation power than SOGAs. In order to improve calculation speed of MOGAs, we propose a new method to easily implement MOGAs as high performance hardware circuits. In the proposed method, we adopt a simple minimal generation gap model as the generation model, which is easy to be pipelined. Since it is difficult to implement niching method and ranking strategy as pipelined circuits, we developed a new selection mechanism which is suitable for hardware implementation. In order to improve search efficiency, our method also includes a parallel execution architecture based on island GA. In this architecture, we use different objective function for each island. Through experiments, we confirmed that our method has higher search efficiency than NSGA-II.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"392","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"381","bibliographicIssueDates":{"bibliographicIssueDate":"2008-01-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicVolumeNumber":"49"}]},"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":"バイオインフォマティックスの情報科学への応用"}]},"weko_creator_id":"1"},"created":"2025-01-18T22:44:51.717359+00:00","id":9722,"links":{}}
