Abstract. We describe the development of a constraint logic programming based system, called CPP, which is capable of generating most preferred plans with respect to a user’s pre...
We develop an Answer Set Programming formalism based on Default Logic. We show that computing generating sets of extensions in this formalism captures all ΣP 2 search problems.
We prove that negative hyper-resolution using any liftable and well-founded ordering refinement is a sound and complete procedure for answering queries in disjunctive logic program...
This paper develops sound modelling and reasoning methods for imperative programs with pointers: heaps are modelled as mappings from addresses to values, and pointer structures are...
The purpose of this paper is to study the problem of complete type inferencing for polymorphic order-sorted logic programs. We show that previous approaches are incomplete even if...
