We survey the most significant results of the literature on distortion from the past 15 years, and highlight important open problems and the most promising avenues of ongoing and future work.","doi":"10.24963/ijcai.2021/589","url":"https://ijcai.org/proceedings/2021/589","pdf":"https://ijcai.org/proceedings/2021/0589.pdf","markdown":"https://ijcai.org/proceedings/2021/589.md","bibtex":"https://ijcai.org/proceedings/2021/bibtex/589","volume":{"slug":"2021","title":"Proceedings of the Thirtieth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 2021","url":"https://ijcai.org/proceedings/2021/","year":2021,"location":"Montreal","dates":"19-27 August 2021","editors":"Prof. Zhi-Hua Zhou","isbn":"978-0-9992411-9-6","publisher":"International Joint Conferences on Artificial Intelligence Organization","doi_prefix":"10.24963/ijcai.2021"},"section":"Survey Track","track":"Survey Track","number":589,"pages":{"first":4294,"last":4301},"keywords":["Agent-based and multi-agent based systems: General"],"videos":[],"references":[],"license_note":"Copyright International Joint Conferences on Artificial Intelligence."}
