The approach involves enumerating a set of physical and causal constraints and enumerating difference causal structures for devices, placing an ordering on these hypothesis types, and carefully controlling the generation of hypotheses. I relate in detail the performance of an implemented causal modeling system on the surprisingly puzzling pocket tire gauge. Results from several examples indicate that the ideas presented support capabilities for maintaining manageably sized hypothesis sets and for making fine distinctions among hypotheses.","doi":null,"url":"https://ijcai.org/proceedings/1989/215","pdf":"https://ijcai.org/proceedings/1989/0215.pdf","markdown":"https://ijcai.org/proceedings/1989/215.md","bibtex":"https://ijcai.org/proceedings/1989/bibtex/215","volume":{"slug":"1989","title":"Proceedings of the Eleventh International Joint Conference on Artificial Intelligence","short_title":"IJCAI 1989","url":"https://ijcai.org/proceedings/1989/","year":1989,"location":"Detroit, Michigan, USA","dates":"August 20-25 1989","editors":"N.
