Similarly, automated reasoning systems can produce formulas that are not necessary for the problem at hand. We concentrate on the problem of unnecessary inference in the context of resolution based systems. In such systems several strategies have been developed that allow for the deletion of clauses without sacrificing completeness. Unfortunately these strategies fail to recognize other frequently generated unnecessary formulas. We will present a generalized subsumption theorem that can be used to recognize such formulas and to develop new deletion methods which retain completeness.","doi":null,"url":"https://ijcai.org/proceedings/1989/58","pdf":"https://ijcai.org/proceedings/1989/0058.pdf","markdown":"https://ijcai.org/proceedings/1989/58.md","bibtex":"https://ijcai.org/proceedings/1989/bibtex/58","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.
