量化布尔公式的对称性

Symmetries of Quantified Boolean Formulas

Manuel Kauers, Martina Seidl

摘要:

虽然对称性是很好地理解布尔公式,并成功地利用在实际的SAT解决,很少有人知道对称性量化布尔公式(QBF)。有一些作品介绍了适应命题对称性破缺技术,与理论只涵盖非常具体的部分QBF对称性。我们提出了一个一般的框架,给出了一个简洁的特征的对称性QBF。我们的框架自然地采用了普遍的和存在的对称性,从而在QBF对称性破缺的一般基础的双重性。

英文摘要:

While symmetries are well understood for Boolean formulas and successfully exploited in practical SAT solving, less is known about symmetries in quantified Boolean formulas (QBF). There are some works introducing adaptions of propositional symmetry breaking techniques, with a theory covering only very specific parts of QBF symmetries. We present a general framework that gives a concise characterization of symmetries of QBF. Our framework naturally incorporates the duality of universal and existential symmetries resulting in a general basis for QBF symmetry breaking.
