We show that every agent, \"rational\" or not, can be modeled as a GEU maxImizer. We then show that we can customize GEU by selectively imposing just the constraints we want. In particular, by show how of Savage's postulates corresponds to constraints on GEU.","doi":null,"url":"https://ijcai.org/proceedings/2003/43","pdf":"https://ijcai.org/proceedings/2003/0043.pdf","markdown":"https://ijcai.org/proceedings/2003/43.md","bibtex":"https://ijcai.org/proceedings/2003/bibtex/43","volume":{"slug":"2003","title":"Proceedings of the Eighteenth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 2003","url":"https://ijcai.org/proceedings/2003/","year":2003,"location":"Acapulco, Mexico","dates":"","editors":"Georg Gottlob","isbn":"","publisher":"International Joint Conferences on Artificial Intelligence","doi_prefix":""},"section":null,"track":"","number":43,"pages":{"first":291,"last":295},"keywords":[],"videos":[],"references":[],"license_note":"Copyright International Joint Conferences on Artificial Intelligence."}
