We present a general method to improve computation of answer sets by analyzing structural properties of normal logic programs. Therefore we use labeled directed graphs associated t...
Abstract. This paper describes a specialised logic for proving specifications in the Java Modeling Language (JML). JML is an interface specification language for Java. It allows ...
The paper studies reductions of propositional theories in equilibrium logic to logic programs under answer set semantics. Specifically we are concerned with the question of how to...
Abstract. The many approaches which have been proposed in the literature for proving the correctness of unfold/fold program transformations, consist in associating suitable well-fo...

A technique for transformation of definite logic programs is presented. A first phase performs an analysis of the extended call/exit patterns of the source program. It is shown tha...
