A Top-Down Procedure for Disjunctive Well-Founded Semantics
Abstract. Skepticism is one of the most important semantic intuitions in artificial intelligence. The semantics formalizing skeptical reasoning in (disjunctive) logic programming i...

Eliminating Disjunction from Propositional Logic Programs under Stable Model Preservation
Abstract. In general, disjunction is considered to add expressive power to propositional logic programs under stable model semantics, and to enlarge the range of problems which can...

Semantics of disjunctive programs with monotone aggregates - an operator-based approach
All major semantics of normal logic programs and normal logic programs with aggregates can be described as fixpoints of the one-step provability operator or of operators that can...

A Purely Model-Theoretic Semantics for Disjunctive Logic Programs with Negation
Abstract. We present a purely model-theoretic semantics for disjunctive logic programs with negation, building on the infinite-valued approach recently introduced for normal logic...

Aggregate Functions in Disjunctive Logic Programming: Semantics, Complexity, and Implementation in DLV
Disjunctive Logic Programming (DLP) is a very expressive formalism: it allows to express every property of finite structures that is decidable in the complexity class ¡£¢¤ (...
