This application problem involves typical features of design problems such as constraints, optimality, a large search space with continuously varying parameters as well as discrete (non-numeric) parameters. There is no known method of comparing elements of the solution space based on a static evaluation function. We have therefore developed a dynamic evaluation function, which attempts to heuristically compare all solutions with one another, as a way of interpreting the evaluation results. This allows us to use an analog of hill-climbing with a simple SELECT-GENERATETEST loop where expert rules are used as \"move generators\" and a similarity metric is used to control or direct the application of the rules for plan modification. Preliminary tests of these ideas indicate that a practical working system can be built.","doi":null,"url":"https://ijcai.org/proceedings/1989/225","pdf":"https://ijcai.org/proceedings/1989/0225.pdf","markdown":"https://ijcai.org/proceedings/1989/225.md","bibtex":"https://ijcai.org/proceedings/1989/bibtex/225","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.
