QRATPre+: Effective QBF Preprocessing via Strong Redundancy Properties [article]

Florian Lonsing, Uwe Egly
2019 arXiv   pre-print
QRATPre+ is the first implementation of these redundancy properties in QRAT and QRAT+ used to simplify QBFs in preprocessing.  ...  These systems rely on strong redundancy properties of clauses and universal literals.  ...  This is made possible by strong redundancy properties. However, the strong redundancy properties of QRAT have not been applied to preprocess QBFs so far.  ...
