Teodor C. Przymusinski - Böcker

This volume is based on papers presented during the ICLP '94 Workshop on Nonmonotonic Extensions of Logic Programming and on papers solicited afterwards from key researchers participating in the workshop. In total 10 carefully refereed, revised, full research papers on semantics and computational aspects of logic programs are included.Logic programs rely on a nonmonotonic operator often referred to as negation by failure or negation by default. The nonmonoticity of this operator allows to apply results from the area of nonmonotonic theories to the investigation of logic programs (and vice versa). This volume is devoted to the interdependence of nonmonotonic formalisms and logic programming.

This book constitutes the thoroughly refereed post-workshop proceedings of the 6th International Workshop on Non-Monotonic Extensions of Logic Programming, NMELP '96, held in Bad Honnef, Germany, in September 1996.The nine full papers presented in the volume in revised version were carefully reviewed and selected from a total of 18 submissions; the set of papers addresses theoretical, applicational and implementational issues and reflects the current state of the art in the area of non-monotonic extensions of logic programming. An introductory survey by the volume editors entitled "Prolegomena to Logic Programming for Non-Monotonic Reasoning" deserves special mentioning; it contains a bibliography listing 136 entries.

This book presents the thoroughly refereed post-workshop proceedings of the Third International Workshop on Logic Programming and Knowledge Representation, LPKR'97, held in Port Jefferson, NY, USA, in October 1997.The eight revised full papers presented have undergone a two-round reviewing process; also included is a comprehensive introduction surveying the state of the art in the area. The volume is divided into topical sections on disjunctive semantics, abduction, priorities, and updates.
