In such situations, the successful agent ~ust mcorporate mto his plans actions which obtain. infox:manon. These plans are intrinsically sketchy to begm w1th and become more specified as the agent proceeds thro~gh ~is plan. A the?IY which allows for such flexible planmng will have to proVIde solutions to two problems: (1) how can an agent reason th~t he knows how to perform an action? (Knowledge Preconditions Problem for Actions) and (2) if an agent must construct an underspecified plan due to incomplete kno:ovledge, when can we say that he can successfully execute h1s plan? (Knowledge Preconditions Problem for Plans) This paper provides solutions to h?th these problei?s. We develop a robust and highly ~xpress1Ve t!teory of ac~on and planning which allows for acnons ofv~g granulanty, primitive as well as complex acts, muln-agent plans, and partially specified plans. We demonstrate tha! this theory lends itself in a natural manner to solunons to the Knowledge Preconditions Problems.","doi":null,"url":"https://ijcai.org/proceedings/1987/182","pdf":"https://ijcai.org/proceedings/1987/0182.pdf","markdown":"https://ijcai.org/proceedings/1987/182.md","bibtex":"https://ijcai.org/proceedings/1987/bibtex/182","volume":{"slug":"1987","title":"Proceedings of the Tenth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 1987","url":"https://ijcai.org/proceedings/1987/","year":1987,"location":"Milan, Italy","dates":"","editors":"John McDermott","isbn":"","publisher":"International Joint Conferences on Artificial Intelligence","doi_prefix":""},"section":"Reasoning","track":"Reasoning","number":182,"pages":{"first":867,"last":873},"keywords":[],"videos":[],"references":[],"license_note":"Copyright International Joint Conferences on Artificial Intelligence."}
