Summary:Abstract: "This paper concerns deductive procedures for abductive reasoning and a variety of ATMSs. Athough de Kleer's basic ATMS [4] has been widely used in AI, the algorithm has not yet been given any formal procedural semantics. Reiter & de Kleer [26] view an ATMS as a kind of abduction in which the best explanation of a formula is defined as a minimal conjunction of hypotheses that explain the formula. However, they do not give any algorithm to compute such minimal explanations of a formula in their CMS that is a generalization of the basic ATMS
In this paper, we use the notion of characteristic clauses [29] to explain clearly the computational aspects of the CMS and the ATMS and to produce an efficient abductive procedure based on linear resolution. By means of this abductive procedure, we give the CMS algorithms for computing minimal explanations in the interpreted approach and for updating them in the compiled approach. We then present algorithms for generating and updating them in the compiled approach. We then present algorithms for generating and updating labels of nodes in an extended ATMS that accepts any formula justifications and literal assumptions
Additionally, proof procedures for a class of nonmonotonic reasoning based on variations of the abductive procedure are also mentioned.
