First we consider properties of the weighted transmission number sequence of a vertex-weighted tree. Let S be a sequence whose terms are pairs of a non-negative integer and a positive integer. The problem determining whether S is the weighted transmission number sequence of a vertex-weighted tree or not, is called w-TNS. We prove that w-TNS is NP-complete, and we show an algorithm using backtracking. This algorithm always gives a correct solution. And, if each transmission number of S is different to the others, then the time complexity of this is only 0( ∣ S ∣ 2).Next we consider the d2-transmission number sequence so that the distance function is defined by a special convex function.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "6261", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "仙石, 正和"}]}, {"nameIdentifiers": [{"nameIdentifier": "19", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "山口, 芳雄"}]}]}, "item_5_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "The Institute of Electronics, Information and Communication Engineers"}]}, "item_5_relation_31": {"attribute_name": "異版である", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://www.ieice.org/jpn/trans_online/", "subitem_relation_type_select": "URI"}}]}, "item_5_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "copyright©1994 IEICE"}]}, "item_5_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_5_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AA10826239", "subitem_source_identifier_type": "NCID"}]}, "item_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "09168508", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Watanabe, Kaoru"}], "nameIdentifiers": [{"nameIdentifier": "6257", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Sengoku, Masakazu"}], "nameIdentifiers": [{"nameIdentifier": "6258", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Tamura, Hiroshi"}], "nameIdentifiers": [{"nameIdentifier": "6259", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Yamaguchi, Yoshio"}], "nameIdentifiers": [{"nameIdentifier": "19", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-07-29"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "e77-a_3_527.pdf", "filesize": [{"value": "526.6 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 526600.0, "url": {"label": "e77-a_3_527.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/1926/files/e77-a_3_527.pdf"}, "version_id": "8fa41ffc-7ec6-46cb-b568-8eb4dc38c565"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "transmission number", "subitem_subject_scheme": "Other"}, {"subitem_subject": "NP-complete problem", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Realization Problems of a Tree with a Transmission Number Sequence", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Realization Problems of a Tree with a Transmission Number Sequence"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "425"], "permalink_uri": "http://hdl.handle.net/10191/6514", "pubdate": {"attribute_name": "公開日", "attribute_value": "2008-07-28"}, "publish_date": "2008-07-28", "publish_status": "0", "recid": "1926", "relation": {}, "relation_version_is_last": true, "title": ["Realization Problems of a Tree with a Transmission Number Sequence"], "weko_shared_id": 2}
