We present sKizzo, a system designed to evaluate and certify Quantified Boolean Formulas (QBFs) by means of propositional skolemization and symbolic reasoning.
Abstract. We describe the instance store, a system for reasoning about individuals (i.e., instances of classes) in OWL ontologies. By using a hybrid reasoner/database architecture,...
We introduce XOR constraints, and show how they enable a theorem prover to reason effectively about security critical subsystems which employ bitwise XOR. Our primary case study is...
Abstract. Basically, the connection of two many-sorted theories is obtained by taking their disjoint union, and then connecting the two parts through connection functions that must...
