部分量词消去的验证

Verification Of Partial Quantifier Elimination

Eugene Goldberg

AI总结:

本文针对部分量词消去(PQE)求解器结果难以验证的问题,提出了一个简单的基于SAT的验证器VerPQE,并通过实验结果证明了其有效性。

摘要:

量词消去(QE)是一个有众多应用的重要问题。遗憾的是,QE在计算上非常困难。此前我们引入了QE的一种推广,称为部分QE(简称PQE)。PQE允许对公式的一部分进行去量词化。PQE的吸引力有两方面。首先,许多重要问题可以用PQE来解决。其次,如果只有一小部分公式被去量词化,PQE可以比QE快得多。为了使PQE实用化,需要一种算法来验证PQE求解器生成的解。在本文中,我们描述了一个非常简单的基于SAT的验证器,称为VerPQE,并提供了一些实验结果。

英文摘要:

Quantifier elimination (QE) is an important problem that has numerous applications. Unfortunately, QE is computationally very hard. Earlier we introduced a generalization of QE called $\mathit{partial}$ QE (or PQE for short). PQE allows to unquantify a $\mathit{part}$ of the formula. The appeal of PQE is twofold. First, many important problems can be solved in terms of PQE. Second, PQE can be drastically faster than QE if only a small part of the formula gets unquantified. To make PQE practical, one needs an algorithm for verifying the solution produced by a PQE solver. In this paper, we describe a very simple SAT-based verifier called $\mathit{VerPQE}$ and provide some experimental results.
