This problem is still open today. Recently it has been discovered that minimization of divergences can determine the allocation of seats. However there are an infinite number of divergences. Since our ultimate objective is to find one and only one apportionment method, it is absolutely necessary for us to determine what divergence to minimize. If we can find an apportionment method that the total number of seats necessary to minimize a divergence is equal to the predetermined house size in the sense of average, then the method might be most desirable. The Webster method will be shown to be closest to it among the existing methods.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1450","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"1442","bibliographicIssueDates":{"bibliographicIssueDate":"2015-06-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"6","bibliographicVolumeNumber":"56"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-19T00:19:48.967720+00:00","id":142353,"links":{}}
