We present a framework for defining abstract interpreters for liveness properties, in particular program termination. The framework makes use of the theory of metric spaces to defi...
We introduce a propositional encoding of the recursive path order with status (RPO). RPO is a combination of a multiset path order and a lexicographic path order which considers pe...
Abstract. The dependency pair method is a powerful method for automatically proving termination of rewrite systems. When used with traditional simplification orders like LPO and K...
Salsa is an invariant checker for speci cations in SAL the SCR Abstract Language. To establish a formula as an invariant without any user guidance Salsa carries out an induction pr...
We introduce the notion of bounded nondeterminism for logic programs and queries. A program and a query have bounded nondeterminism if there are finitely many refutations for the...
