Logic Programming and Automated Reasoning: 4th International Conference, LPAR'93, St.Petersburg, Russia, July 13-20, 1993. Proceedings [Paperback]

LPAR is an international conference series aimed at bringingtogether researchers interested in logic programming andautomated reasoning. The research in logic programming grewout of the research in automated reasoning in the early1970s. Later, the implementation techniques known from logicprogramming were used in implementing theorem provingsystems. Results from both fields applied to deductivedatabases.This volume contains the proceedings of LPAR '93, which wasorganized by the Russian Association for Logic Programming.The volume contains 35 contributed papers selected from 84submissions, together with an invited paper by Peter Wegnerentitled Reasoning versus modeling in computer science .Entailment and disentailment of order-sorted feature constraints.- Computing extensions of default logic  Preliminary report.- Prolog with arrays and bounded quantifications.- Linear 01 inequalities and extended clauses.- Search space pruning by checking dynamic term growth.- A proof search system for a modal substructural logic based on labelled deductive systems.- Consistency checking of automata functional specifications.- Yet another application for Toupie: Verification of mutual exclusion algorithms.- Parsing with DCG-terms.- A first order resolution calculus with symmetries.- Ordered paramodulation and resolution as decision procedure.- Static analysis of Prolog with cut.- A new type theory for representing logics.- Verification of Switch-level designs with many-valued logic.- Deciding in HFS-theory via linear integer programming.- The completion of typed logic programs and SLDNF-resolution.- Increasing the versatility of heuristic based theorem provers.- Sequentialization of parallel logic programs with mode analysis.- Refinements and extensions of model elimination.- Executable specifications based on dynamic algebras.- Generic resolution in propositional modal systems.- Optimized trlã>
