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...

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...

A backjumping technique for Disjunctive Logic Programming
In this work we present a backjumping technique for Disjunctive Logic Programming (DLP) under the Answer Set Semantics. It builds upon related techniques that had originally been p...
