A Common View on Strong, Uniform, and Other Notions of Equivalence in Answer-Set Programming
Logic programming under the answer-set semantics nowadays deals with numerous different notions of equivalence between programs. This is due to the fact that equivalence for substi...

Uniform Equivalence of Logic Programs under the Stable Model Semantics
In recent research on nonmonotonic logic programming, repeatedly strong equivalence of logic programs P and Q has been considered, which holds if the programs P ∪ R and Q ∪ R h...

Towards Implementations for Advanced Equivalence Checking in Answer-Set Programming
Abstract. In recent work, a general framework for specifying program correspondences under the answer-set semantics has been defined. The framework allows to define different not...

Alternative Characterizations for Program Equivalence under Answer-Set Semantics: Preliminary Report
Logic programs under answer-set semantics constitute an important tool for declarative problem solving. In recent years, two research issues received growing attention. On the one ...
