We analyze what kind of information this metric carries and how it can be utilized for constructing lifted delete-free relaxation heuristics. In particular, we prove how the action dynamics influence the distances between objects. As a corollary, we derive a lower bound on the length of any plan. Finally, we apply our theoretical findings on the Gaifman graphs to improve the delete-free relaxation heuristics induced by PDDL homomorphisms.<\/jats:p>","DOI":"10.3233\/faia230378","type":"book-chapter","created":{"date-parts":[[2023,9,29]],"date-time":"2023-09-29T09:10:38Z","timestamp":1695978638000},"source":"Crossref","is-referenced-by-count":0,"title":["Gaifman Graphs in Lifted Planning"],"prefix":"10.3233","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7967-7126","authenticated-orcid":false,"given":"Rostislav","family":"Hor\u010d\u00edk","sequence":"first","affiliation":[{"name":"Czech Technical University in Prague, Faculty of Electrical Engineering, Prague, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2383-9477","authenticated-orcid":false,"given":"Daniel","family":"Fi\u0161er","sequence":"additional","affiliation":[{"name":"Saarland University, Saarland Informatics Campus, Saarbr\u00fccken, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","ECAI 2023"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/FAIA230378","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,29]],"date-time":"2023-09-29T09:10:40Z","timestamp":1695978640000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/FAIA230378"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,9,28]]},"ISBN":["9781643684369","9781643684376"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/faia230378","relation":{},"ISSN":["0922-6389","1879-8314"],"issn-type":[{"type":"print","value":"0922-6389"},{"type":"electronic","value":"1879-8314"}],"subject":[],"published":{"date-parts":[[2023,9,28]]}}}
