Foundations of Software Technology and Theoretical Computer Science: 13th Conference, Bombay, India, December 15-17, 1993. Proceedings [Paperback]

For more than a decade, Foundations of Software Technologyand Theoretical Computer Science Conferences have beenproviding an annual forum for the presentation of newresearch results in India and abroad. This year, 119 papersfrom 20 countries were submitted. Each paper was reviewed byat least three reviewers, and 33 papers were selected forpresentation and included in this volume, grouped into partson type theory, parallel algorithms, term rewriting, logicand constraint logic programming, computational geometry andcomplexity, software technology, concurrency, distributedalgorithms, and algorithms and learning theory. Alsoincluded in the volume are the five invited papers presentedat theconference.Some observations about the nature of computer science.- Essential intersection type assignment.- Label-selective ?-calculus syntax and confluence.- Conventional and uniqueness typing in graph rewrite systems.- A meta-language for typed object-oriented languages.- Preemption in concurrent systems.- Local versus non-local computation of length of digitized curves.- Data-independences of parallel random access machines.- Proving termination of logic programs by transforming them into equivalent term rewriting systems.- Completeness of hierarchical combinations of term rewriting systems.- Higher-order and semantic unification.- A conservative extension of first-order logic and its applications to theorem proving.- Well-founded Ordered Search (extended abstract).- A real-time interval logic and its decision procedure.- On the semantics of optimization predicates in CLP languages.- Incremental algorithms for constraint solving and entailment over rational trees.- Proximity problems and the Voronoi diagram on a rectilinear plane with rectangular obstacles.- Feasibility of design in stereolithography.- Compact location problems.- On some communication complexity problems related to threshold functions.- Recursiveness over the complex nulÓf
