A General Theory of Confluent Rewriting Systems for Logic Programming and Its Applications
註釋Recently, Brass and Dix showed (Journal of Automated Reasoning 20(1), 1998) that the wellfounded semantics WFS can be defined as a confluent calculus of transformation rules. This lead not only to a simple extension to disjunctive programs (Journal of Logic Programming 38(3), 1999), but also to a new computation of the wellfounded semantics which is linear for a broad class of programs. We take this approach as a starting point and generalize it considerably by
