Introducing Autarkies for DQCNF.
2019
Autarkies for SAT can be used for theoretical studies, pre-processing and inprocessing. They generalise satisfying assignments by allowing to leave some clauses "untouched" (no variable assigned). We introduce the natural generalisation to DQCNF (dependency-quantified boolean CNF), with the perspective of SAT translations for special cases. Finding an autarky for DQCNF is as hard as finding a satisfying assignment. Fortunately there are (many) natural autarky-systems, which allow restricting the range of autarkies to a more feasible domain, while still maintaining the good general properties of arbitrary autarkies. We discuss what seems the most fundamental autarky systems, and how the related reductions can be found by SAT solvers.
