Automated Reasoning with Analytic Tableaux and Related Methods : International Conference

ThisvolumecontainsaselectionofpaperspresentedattheInternationalConf- ence on Analytic Tableaux and Related Methods (TABLEAUX99) held on June 7-11, 1999 at the Inn at Saratoga, Saratoga Springs, NY, USA. This conference was the continuation of international meetings on Theorem Proving with A- lytic Tableaux and Related Methods held in Lautenbach near Karlsruhe (1992), Marseille (1993), Abingdon near Oxford (1994), St. Goar near Koblenz (1995), Terrasini near Palermo (1996), Pont- a-Mousson near Nancy (1997), and Oist- wijk near Tilburg (1998). TABLEAUX99 marks the ?rst time the conference has been held in North America. Tableau and related methods have been found to be convenient and e?ective for automating deduction in various non-standard logics as well as in classical logic. Examples taken from this meeting alone include temporal, description, tense, quantum, modal, projective, hybrid, intuitionistic, and linear logics. - eas of application include veri?cation of software and computer systems, ded- tive 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 devel- ment and applications - of the mechanization of reasoning with tableaux and related methods.
