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 Impact of Stratification on the Complexity of Nonmonotonic Reasoning
ABSTRACT. This paper investigates the problem of finding subclasses of nonmonotonic reasoning which can be implemented efficiently. The ability to "define" propositions u...

Extracting Programs from Constructive HOL Proofs Via IZF Set-Theoretic Semantics
Church's Higher Order Logic is a basis for proof assistants -- HOL and PVS. Church's logic has a simple set-theoretic semantics, making it trustworthy and extensible. We ...

Modular Nonmonotonic Logic Programming Revisited
Recently, enabling modularity aspects in Answer Set Programming (ASP) has gained increasing interest to ease the composition of program parts to an overall program. In this paper, ...

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...
