ALPUK92: Proceedings of the 4th UK Conference on Logic Programming, London, 30 March – 1 April 1992

Since its conception nearly 20 years ago, logic programming has been developed to the point where it now plays an important role in areas such as database theory, artificial intelligence and software engineering. There are, however, still many outstanding research issues which need to be addressed, and the UK branch of the Association for Logic Programming was set up to provide a forum where the flourishing research community could discuss important issues which were often by- passed at the larger international conferences. This volume contains the invited papers, refereed papers and tutorials presented at the 4th ALPUK Conference, which aimed to broaden the frontiers of logic programming by encouraging interaction between it and other related disciplines. The papers cover a variety of technical areas, including concurrent logic languages and their semantics, applications of logic languages to other (non-classical) logical systems, modules, types and error-handling, and the distributed execution of Prolog programs. The wide scope of the papers refelects the breadth of interest in this important area of computer science. ALPUK 92 provides a comprehensive overview of current progress being made in logic programming research. It will be of interest to all workers in the field, especially researchers, postgraduate students, and research and development workers in industry.
