Backdoors to Tractable Answer-Set Programming
We present a unifying approach to the efļ¬cient evaluation of propositional answer-set programs. Our approach is based on backdoors which are small sets of atoms that represent ā...

Towards Parameterized Regular Type Inference Using Set Constraints
We propose a method for inferring parameterized regular types for logic programs as solutions for systems of constraints over sets of finite ground Herbrand terms (set constraint s...

Stable models and circumscription
The concept of a stable model provided a declarative semantics for Prolog programs with negation as failure and became a starting point for the development of answer set programmi...

Manifold Answer-Set Programs for Meta-reasoning
Abstract. In answer-set programming (ASP), the main focus usually is on computing answer sets which correspond to solutions to the problem represented by a logic program. Simple re...

A New Perspective on Stable Models
The deļ¬nition 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...
