Automated Reasoning with Analytic Tableaux and Related Methods Bernhard Beckert (ed.) This volume contains the research papers presented at the International Conference on Automated Reasoning with Analytic Tableaux and Related Methods (TABLEAUX 2005) held 14-17 September 2005 in Koblenz, Germany. Tableau methods are a convenient formalism for automating deduction in various non-standard logics as well as in classical logic. Areas of application include verification of software and computer systems, deductive databases, knowledge representation and its required inference engines, and system diagnosis. The conference brought together researchers interested in all aspects - theoretical foundations, implementation techniques, systems development and applications - of the mechanization of reasoning with tableaux and related methods.
