In this paper we outline QuBE7’s main features, describing first the options of the preprocessors, and then giving some details about how the core search-based solver (i) performs unit and pure literal propagation; and (ii) performs the “Conflict Analysis procedure” for non-chronological backtracking, generalised from the SAT to the QBF case. We conclude with the experimental evaluation, showing that QuBE7.0 is the a state-of-the-art single-engine QBF solver.
