CADE-21 21st International Conference on Automated Deduction International University Bremen, Germany July 17-20, 2007 (workshops July 15-16) http://www.cadeconference.org/meetings/cade21 Call for Participation Call for Nominations for Bledsoe Student Travel Awards CADE is the major forum for the presentation of research in all aspects of automated deduction. - Logics of interest include propositional, first-order, equational, higher-order, classical, intuitionistic, constructive, modal, temporal, many-valued, substructural, description, and meta-logics, logical frameworks, type theory and set theory. - Methods of interest include resolution, tableaux, term rewriting, induction, unification, constraint solving, SAT solving, decision procedures, saturation, model generation, model checking, natural deduction, sequent calculi, proof planning, proof presentation, proof checking, and explanation. - Applications of interest include hardware and software development, systems analysis and verification, deductive databases, functional and logic programming, computer mathematics, natural language processing, computational linguistics, robotics, planning, knowledge representation, and other areas of AI.
