In this paper, we propose algorithms to generate polyiamonds for p6 tiling, i.e., those covering the plane by only 6-fold rotations around two rotation centers. The conventional methods are basically trial and error, i.e., they repeat generating polyiamonds and checking whether the shapes have been already generated. Our approach is based on the reverse search, in which we design rules to generate the next. This technique has the following two characteristics: (1) No trial and error, which implies that we can reduce the computation time. (2) No need to store already generated polyiamonds. Thus, we can also reduce the space complexity. We also implement the algorithm and generate 26,875 polyiamonds with n = 21 equilateral triangles, while the conventional methods generated 29 polyiamonds with n = 9 equilateral triangles.","subitem_description_type":"Other"}]},"item_120_description_29":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_120_description_30":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_120_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24561/00016436","subitem_identifier_reg_type":"JaLC"}]},"item_120_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"埼玉大学工学部"}]},"item_120_publisher_12":{"attribute_name":"出版者名（別言語）","attribute_value_mlt":[{"subitem_publisher":"Faculty of Engineering, Saitama University"}]},"item_120_text_27":{"attribute_name":"版","attribute_value_mlt":[{"subitem_text_value":"[出版社版]"}]},"item_120_text_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"YAMANE, Shogo"},{"subitem_text_value":"HORIYAMA, Takashi"}]},"item_120_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"KY-AN00095842-43-05"}]},"item_120_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"埼玉大学大学院理工学研究科"},{"subitem_text_value":"埼玉大学大学院理工学研究科"}]},"item_120_text_5":{"attribute_name":"著者 所属(別言語)","attribute_value_mlt":[{"subitem_text_value":"Graduate School of Science and Engineering, Saitama University"},{"subitem_text_value":"Graduate School of Science and Engineering, Saitama University"}]},"item_120_text_9":{"attribute_name":"年月次","attribute_value_mlt":[{"subitem_text_value":"2009"}]},"item_120_version_type_28":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山根, 祥悟"},{"creatorName":"ヤマネ, ショウゴ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"堀山, 貴史"},{"creatorName":"ホリヤマ, タカシ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-01-24"}],"displaytype":"detail","filename":"KY-AN00095842-43-05.pdf","filesize":[{"value":"725.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KY-AN00095842-43-05.pdf","url":"https://sucra.repo.nii.ac.jp/record/16442/files/KY-AN00095842-43-05.pdf"},"version_id":"7221f834-7302-4c98-b803-ecc0363801c5"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Algorithms","subitem_subject_scheme":"Other"},{"subitem_subject":"Tiling","subitem_subject_scheme":"Other"},{"subitem_subject":"Symmetry","subitem_subject_scheme":"Other"},{"subitem_subject":"Reverse Search","subitem_subject_scheme":"Other"},{"subitem_subject":"Polyiamonds","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"逆探索に基づくp6タイリングの生成＜研究成果報告＞","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"逆探索に基づくp6タイリングの生成＜研究成果報告＞"}]},"item_type_id":"120","owner":"3","path":["522"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-02-24"},"publish_date":"2014-02-24","publish_status":"0","recid":"16442","relation_version_is_last":true,"title":["逆探索に基づくp6タイリングの生成＜研究成果報告＞"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-15T18:49:16.645309+00:00"}
