Abstract. In this paper we formulate (qualitative) spatial reasoning within the framework of numerical optimisation, and develop an approach that extends Constraint Logic Programming (CLP) to support variables that range over spatial domains. The crux of our approach is extending standard unification by the mechanism of attributed variables, and using specialised numerical optimisation algorithms in a stateless manner. We prove that our approach is fully consistent with the semantics of CLP, and demonstrate a range of powerful spatial reasoning features.
