A method of deductive learning is developed to control deductive inference Our goal is to im prove problem solving time by experience when that experience monotonically adds knowledge to the knowledge base In particular for deductive reasoning systems where partial results are saved dur ing a derivation and at least some partial results are themselves deduction rules we suggest ways of taking m...

We present the Why/Krakatoa/Caduceus set of tools for deductive veri cation of Java and C source code.

We consider the problem of extending temporal deductive databases with stratified negation. We argue that the classical stratification test for deductive databases is too restrictive when one shifts attention to the temporal case. Moreover, as we demonstrate, the (more general) local stratification approach is impractical: detecting whether a temporal deductive database is locally stratified is...

This paper summarizes our experiences from an exercise in deductive verification of functional properties of automotive embedded Ccode in an industrial setting. We propose a formal requirements model that supports the way C-code requirements are currently written at Scania. We describe our work, for a safety-critical module of an embedded system, on formalizing its functional requirements and v...
