# Advanced Conflict-Driven Disjunctive Answer Set Solving

Martin Gebser, Benjamin Kaufmann, Torsten Schaub

## Abstract

We introduce a new approach to disjunctive ASP solving that aims at an equitable interplay between generating and testing solver units. To this end, we develop novel characterizations of answer sets and unfounded sets allowing for a bidirectional dynamic information exchange between solver units for orthogonal tasks. This results in the new multi-threaded disjunctive ASP solver claspD-2, greatly improving the performance of existing systems.
