对于 SAT 和 QBF 公式,在将公式传递到实际求解算法之前,应用了许多技术来减少/修改公式的变量和子句的数量。众所周知,这些预处理技术通常可以将求解器的计算时间减少几个数量级。在本文中,我们将 SAT 和 QBF 问题的不同预处理技术推广到依赖量化布尔公式 (DQBF),并描述它们需要如何适应 DQBF 求解器核心。我们证明了它们对于基于 CNF 和非 CNF 的 DQBF 算法的有效性。
For SAT and QBF formulas many techniques are applied in order to reduce/modify the number of variables and clauses of the formula, before the formula is passed to the actual solving algorithm. It is well known that these preprocessing techniques often reduce the computation time of the solver by orders of magnitude. In this paper we generalize different preprocessing techniques for SAT and QBF problems to dependency quantified Boolean formulas (DQBF) and describe how they need to be adapted to work with a DQBF solver core. We demonstrate their effectiveness both for CNF- and non-CNF-based DQBF algorithms.
