In this paper we discuss the question which properties of a formally verified component are preserved when the component is changed due to an adaption to a new use. More specific...
A refutation mechanism is introduced into logic programming, dual to the usual proof mechanism; then negation is treated via refutation. A four-valued logic is appropriate for the...
In this paper, we present a framework for automatic generation of CHR solvers given the logical specification of the constraints. This approach takes advantage of the power of tab...
We consider software verification of imperative programs by theorem proving in higher-order separation logic. Of particular interest are the difficulties of encoding and reasoning ...
In this paper we describe an improved formalisation of slicing in WSL transformation theory and apply the result to a particularly challenging slicing problem: the SCAM mug [1]. W...
