Backtracking is implemented with a single stack and no copying of activation frames is needed. Lists are represented as arrays of pointers; the garbage collector for this representation requires no additional memory. Restrictions on variable values are accomplished by using 'semi-defined' structures. These methods have enabled to achieve the high efficiency of the system work.","doi":null,"url":"https://ijcai.org/proceedings/1975/90","pdf":"https://ijcai.org/proceedings/1975/0090.pdf","markdown":"https://ijcai.org/proceedings/1975/90.md","bibtex":"https://ijcai.org/proceedings/1975/bibtex/90","volume":{"slug":"1975","title":"Proceedings of the Fourth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 1975","url":"https://ijcai.org/proceedings/1975/","year":1975,"location":"Tbilisi, Georgia, USSR","dates":"","editors":"Patrick Winston and Carl Hewitt","isbn":"","publisher":"International Joint Conferences on Artificial Intelligence","doi_prefix":""},"section":"A.I.
