Abstract

This paper provides a method for generating a proof tree from an instance and a general logic program viz one which includes negative literals. The method differs from previous work in the field in that negative literals are first unfolded and then transformed using De Morgan's laws so that the tree explicitly includes negative rules. The method is applied to a real-world example - a large executable specification providing rules for separation for two aircraft. Given an instance of a pair of aircraft whose flight paths potentially violate seperation rules,the tree contains both positive and negative rules which contribute to the proof.
