Answer Sets for Consistent Query Answering in Inconsistent Databases
A relational database is inconsistent if it does not satisfy a given set of integrity constraints. Nevertheless, it is likely that most of the data in it is consistent with the co...

Perspective reformulations of mixed integer nonlinear programs with indicator variables
Abstract. We study mixed integer nonlinear programs (MINLP)s that are driven by a collection of indicator variables where each indicator variable controls a subset of the decision ...

Answer Set Programming with Constraints Using Lazy Grounding
The paper describes a novel methodology to compute stable models in Answer Set Programming. The proposed approach relies on a bottom-up computation that does not require a prelimin...

Designing, Specifying and Querying Metadata for Virtual Data Integration Systems
Abstract. We show how to specify and use the metadata for a virtual and relational data integration system under the local-as-view (LAV) approach. We use XML and RuleML for represe...

Tractable Answer-Set Programming with Weight Constraints: Bounded Treewidth Is not Enough
Cardinality constraints or, more generally, weight constraints are well recognized as an important extension of answer-set programming. Clearly, all common algorithmic tasks relat...
