However, if a learning system generates and saves all macro-operators extracted from worked examples, they will increase explosively and eventually its problem solving will be less efficient than even a non-learning system. Thus, it is very important for macro-operator learning to select only the effective macro-operators. To cope with this problem, we propose a new method to select macrooperators by Perfect Causality, a new heuristic, and generalization of them with EBG. Both in classical robot planning and solving algebraic equations, we made the experiments using a selective macro-learning system with Perfect Causality, a non-selectively macrolearning system and a non-learning system. The experimental results verify much higher efficiency of the selective learning system than the other two systems over a lot of various problems. Finally, we discuss Perfect Causality as an operationality criterion in EBL perspective.","doi":null,"url":"https://ijcai.org/proceedings/1989/96","pdf":"https://ijcai.org/proceedings/1989/0096.pdf","markdown":"https://ijcai.org/proceedings/1989/96.md","bibtex":"https://ijcai.org/proceedings/1989/bibtex/96","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.
