Head-Elementary-Set-Free Logic Programs
Abstract. The recently proposed notion of an elementary set yielded a refinement of the theorem on loop formulas, telling us that the stable models of a disjunctive logic program ...

Casting Away Disjunction and Negation under a Generalisation of Strong Equivalence with Projection
Abstract. In answer-set programming (ASP), many notions of program equivalence have been introduced and formally analysed. A particular line of research in this direction aims at s...

A Causal Logic of Logic Programming
The causal logic from (Bochman 2003b) is shown to provide a natural logical basis for logic programming. More exactly, it is argued that any logic program can be seen as a causal ...

Logic Programs With Monotone Cardinality Atoms
We investigate mca-programs, that is, logic programs with clauses built of monotone cardinality atoms of the form kX , where k is a non-negative integer and X is a finite set of ...

On the Role of Negation in Choice Logic Programs
We introduce choice logic programs as negation-free datalog programs that allow rules to have exclusive-only (possibly empty) disjunctions in the head. Such programs naturally mod...
