The key idea is to translate a given causal graph into an autonomous dynamical system and to analyze equilibrium points in the system. The method requires no numerical information and it has the advantage of computing the conditions under which a certain equilibrium type holds and when equilibrium type-transitions occur. The method is firmly based on mathematical grounds, and the result is guaranteed to be valid for linear systems under the specified conditions.","doi":null,"url":"https://ijcai.org/proceedings/1997/80","pdf":"https://ijcai.org/proceedings/1997/0080.pdf","markdown":"https://ijcai.org/proceedings/1997/80.md","bibtex":"https://ijcai.org/proceedings/1997/bibtex/80","volume":{"slug":"1997","title":"Proceedings of the Fifteenth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 1997","url":"https://ijcai.org/proceedings/1997/","year":1997,"location":"Nagoya, Japan","dates":"","editors":"Martha E.
