Multilevel selection recently proposed by Sober and Wilson is a new comprehensive theory explaining it. Group-level selection and within-group individual-level selection are supposed to work simultaneously, in which groups are defined on a trait-by-trait basis. This is the main idea of multilevel selection (MS). Some of the previous studies have shown that periodic group-restructuring is necessary to keep MS working. We constructed an agent-based model based on the N-player prisoner\u0027s dilemma (NPD) for MS with dynamic group-restructuring and conducted evolutionary experiments. It has been shown that even if adopting random group-restructuring method, cooperation evolves when group sizes are small, because the benefits of cooperators are sometimes higher than the costs in that case. It has also been shown that cooperation quickly evolves in the case that non-random group-restructuring method is adopted and in the case that group-restructuring is conducted every when the fraction of cooperators decreases. Also, we have analyzed our models in terms of kin selection and in terms of variance partition based on Price equation.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_10_identifier_60": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2237/10511"}]}, "item_10_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "情報処理学会", "subitem_publisher_language": "ja"}]}, "item_10_rights_12": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "ここに掲載した著作物の利用に関する注意 本著作物の著作権は（社）情報処理学会に帰属します。本著作物は著作権者である情報処理学会の許可のもとに掲載するものです。ご利用に当たっては「著作権法」ならびに「情報処理学会倫理綱領」に従うことをお願いいたします。 ", "subitem_rights_language": "ja"}, {"subitem_rights": "Notice for the use of this material The copyright of this material is retained by the Information Processing Society of Japan (IPSJ).
