Fixed-Parameter Complexity of Semantics for Logic Programs
In the paper we establish the xed-parameter complexity for several parameterized decision problems involving models, supported models and stable models of logic programs. We also e...

Yet Another Proof of the Strong Equivalence Between Propositional Theories and Logic Programs
Recently, the stable model semantics was extended to the syntax of arbitrary propositional formulas, which are beyond the traditional rule form. Cabalar and Ferraris, as well as Ca...

Computing stable models: worst-case performance estimates
Abstract. We study algorithms for computing stable models of propositional logic programs and derive estimates on their worst-case performance that are asymptotically better than t...

A New Perspective on Stable Models
The definition of a stable model has provided a declarative semantics for Prolog programs with negation as failure and has led to the development of answer set programming. In th...

Pbmodels - Software to Compute Stable Models by Pseudoboolean Solvers
Abstract. We describe a new software, pbmodels, that uses pseudo-boolean constraint solvers (PB solvers) to compute stable models of logic programs with weight atoms. To this end, ...
