Generalised Interpolation by Solving Recursion-Free Horn Clauses
arXiv:1303.7378 · doi:10.4204/EPTCS.169.5
Abstract
In this paper we present InterHorn, a solver for recursion-free Horn clauses. The main application domain of InterHorn lies in solving interpolation problems arising in software verification. We show how a range of interpolation problems, including path, transition, nested, state/transition and well-founded interpolation can be handled directly by InterHorn. By detailing these interpolation problems and their Horn clause representations, we hope to encourage the emergence of a common back-end interpolation interface useful for diverse verification tools.
