dl2asp: Implementing Default Logic via Answer Set Programming
In this paper, we show that Reiter’s default logic in the propositional case can be translated into answer set programming by identifying the internal relationships among formula...

Reasoning Credulously and skeptically within a single extension
Consistency-based approaches in nonmonotonic reasoning may be expected to yield multiple sets of default conclusions for a given default theory. Reasoning about such extensions is ...

Reasoning with Sets of Defaults in Default Logic
We present a general approach for representing and reasoning with sets of defaults in default logic, focussing on reasoning about preferences among sets of defaults. First, we con...

Reasoning about Actions and Planning with Preferences Using Prioritized Default Theory
This paper shows how action theories, expressed in an extended version of the language B, can be naturally encoded using Prioritized Default Theory. We also show how prioritized d...

Splitting a Default Theory
This paper presents mathematical results that can sometimes be used to simplify the task of reasoning about a default theory, by \splitting it into parts." These so-called Sp...

Soundness and Completeness of a Logic Programming Approach to Default Logic
We present a method of representing some classes of default theories as normal logic programs. The main point is that the standard semantics (i.e. SLDNF-resolution) computes answe...

Compiling Reasoning with and about Preferences into Default Logic
We address the problem of introducing preferences into default logic. Two approaches are given, one a generalisation of the other. In the first approach, an ordered default theory...

On the Compilation of Possibilistic Default Theories
Handling exceptions represents one of the most important problems in Artificial Intelligence. Several approaches have been proposed for reasoning on default theories. This paper f...

Generality and Equivalence Relations in Default Logic
Generality or refinement relations between different theories have important applications to generalization in inductive logic programming, refinement of ontologies, and coordin...

The Complexity of Model Checking for Propositional Default Logics
Abstract. Default logic is one of the most widely used formalisms to formalize commonsense reasoning. In this paper we analyze the complexity of deciding whether a propositional in...
