Discovering Classes of Strongly Equivalent Logic Programs
We report on a successful experiment of computeraided theorem discovery in the area of logic programming with answer set semantics. Specifically, with the help of computers, we d...

Sound and Complete Inference Rules for SE-Consequence
The notion of strong equivalence on logic programs with answer set semantics gives rise to a consequence relation on logic program rules, called SE-consequence. We present a sound...

Component-Based Answer Set Programming
In previous work we have discussed the importance of identifying the cycles that occur in a logic program under the answer set semantics, and the connections between cycles, that w...

Guarded Open Answer Set Programming with Generalized Literals
Abstract. We extend the open answer set semantics for programs with generalized literals. Such extended programs (EPs) have interesting properties, e.g. the ability to express infi...

Approximating Extended Answer Sets
Abstract. We present an approximation theory for the extended answer set semantics, using the concept of an approximation constraint. Intuitively, an approximation constraint, whil...

LPForget: A System of Forgetting in Answer Set Programming
Abstract. A novel declarative approach of forgetting in answer set programming (ASP) has been proposed recently. In this paper we report a system prototype of forgetting in ASP, ca...

Temporal Equilibrium Logic: A First Approach
In this paper we introduce an extension of Equilibrium Logic (a logical characterisation of the Answer Set Semantics for logic programs) consisting in the inclusion of modal tempor...

Splitting a Logic Program
In many cases, a logic program can be divided into two parts, so that one of them, the \bottom" part, does not refer to the predicates de ned in the \top" part. The \bot...

Representing Transition Systems by Logic Programs
This paper continues the line of research on representing actions, on the automation of commonsense reasoning and on planning that deals with causal theories and with action langua...

Solving Hard Disjunctive Logic Programs Faster (Sometimes)
Disjunctive Logic Programming (DLP) under the consistent answer set semantics is an advanced formalism for knowledge representation and reasoning. It is, under widely believed assu...
