Abstract. We propose a generic type system for the Constraint Handling Rules (CHR), a rewriting rule language for implementing constraint solvers. CHR being a high-level extension ...
The extended answer set semantics for logic programs allows for the defeat of rules to resolve contradictions. We propose a refinement of these semantics based on a preference rel...

We describe the Consistency Extractor System (ConsEx) that computes consistent answers to Datalog queries with negation posed to relational databases that may be inconsistent with...
Many DSP and image processing embedded systems have hard memory constraints which makes it difficult to find a good task assignment and scheduling which fulfill these constrain...
Abstract. We illustrate the potential of conditional hedge transformations in Web-related applications on the example of PρLog: an extension of logic programming with advanced rul...
