We model MPAs whose values are expressed by formulas of linear temporal logic (LTL) and define comparison for both joint plans and individual plans. We introduce different evaluation criteria for individual plans including an optimistic (risk-seeking) criterion, a pessimistic (risk-averse) one, and two criteria based on the use of anticipated responsibility. We provide complexity results for a variety of MPA problems.","doi":"10.24963/ijcai.2023/47","url":"https://ijcai.org/proceedings/2023/47","pdf":"https://ijcai.org/proceedings/2023/0047.pdf","markdown":"https://ijcai.org/proceedings/2023/47.md","bibtex":"https://ijcai.org/proceedings/2023/bibtex/47","volume":{"slug":"2023","title":"Proceedings of the Thirty-Second International Joint Conference on Artificial Intelligence","short_title":"IJCAI 2023","url":"https://ijcai.org/proceedings/2023/","year":2023,"location":"Macao, SAR","dates":"19-25 August 2023","editors":"Edith Elkind","isbn":"978-1-956792-03-4","publisher":"International Joint Conferences on Artificial Intelligence Organization","doi_prefix":"10.24963/ijcai.2023"},"section":"AI Ethics, Trust, Fairness","track":"Main Track","number":47,"pages":{"first":418,"last":426},"keywords":["AI Ethics, Trust, Fairness: ETF: Moral decision making","Knowledge Representation and Reasoning: KRR: Knowledge representation languages","Agent-based and Multi-agent Systems: MAS: Normative systems"],"videos":[],"references":[],"license_note":"Copyright International Joint Conferences on Artificial Intelligence."}
