English abstract:
Epistemic Logic Programs (ELPs) are an extension of Answer Set Programming (ASP) with epistemic
operators that allow for a form of meta-reasoning, that is, reasoning over multiple possible worlds. Existing
ELP solving approaches generally rely on making multiple calls to an ASP solver in order to evaluate the
ELP. However, in this paper, we show that there also exists a direct translation from ELPs into non-ground
ASP with bounded arity. The resulting ASP program can thus be solved in a single shot.We then implement
this encoding method, using recently proposed techniques to handle large, non-ground ASP rules, into the
prototype ELP solving system "selp", which we present in this paper. This solver exhibits competitive
performance on a set of ELP benchmark instances.
