Query: Catching the Ouroboros: On Debugging Non-ground Answer-Set Programs   An important issue towards a broader acceptance of answer-set programming
(ASP) is the deployment of tools which support the programmer during the coding
phase. In particular, methods for debugging an answer-set program are
recognised as a crucial step in this regard. Initial work on debugging in ASP
mainly focused on propositional programs, yet practical debuggers need to
handle programs with variables as well. In this paper, we discuss a debugging
technique that is directly geared towards non-ground programs. Following
previous work, we address the central debugging question why some
interpretation is not an answer set. The explanations provided by our method
are computed by means of a meta-programming technique, using a uniform encoding
of a debugging request in terms of ASP itself. Our method also permits programs
containing comparison predicates and integer arithmetics, thus covering a
relevant language class commonly supported by all state-of-the-art ASP solvers.
