In the symbolic analysis of security protocols, two classical notions of knowledge, deducibility and indistinguishability, yield corresponding decision problems. We propose a proce...
Abstract. This article describes the first public version of the satisfiability modulo theory (SMT) solver veriT. It is open-source, proof-producing, and complete for quantifier-fr...
Abstract This work studies the properties of finite automata recognizing vectors with real components, encoded positionally in a given integer numeration base. Such automata are us...
Scalable handling of real arithmetic is a crucial part of the verification of hybrid systems, mathematical algorithms, and mixed analog/digital circuits. Despite substantial advanc...
Abstract. An extension of the superposition-based E-prover [8] is described. The extension allows terms with integer exponents [3] in the input language. Obviously, this possibilit...
Abstract. We give an optimal (exptime), sound and complete tableaubased algorithm for deciding satisfiability for propositional dynamic logic. Our main contribution is a sound meth...
Abstract. Saturation-based calculi such as superposition can be successfully instantiated to decision procedures for many decidable fragments of first-order logic. In case of termi...
The inverse method is a generic proof search procedure applicable to non-classical logics satisfying cut elimination and the subformula property. In this paper we describe a genera...
