摘要翻译：
本文提出了一种独立的SAT预处理器，它能够执行大多数已知的预处理技术。对SAT中的公式进行预处理对性能很重要，因为可以消除冗余。预处理器是SAT求解器riss的一部分，被称为协处理器。不仅riss，而且MiniSat2.2也从中受益，因为MiniSat的SatELite预处理器没有实现最新的技术。协处理器通过使用更先进的技术，可以进一步减少公式中的冗余，提高整体求解性能。

英文摘要：
  In this work a stand-alone preprocessor for SAT is presented that is able to perform most of the known preprocessing techniques. Preprocessing a formula in SAT is important for performance since redundancy can be removed. The preprocessor is part of the SAT solver riss and is called Coprocessor. Not only riss, but also MiniSat 2.2 benefit from it, because the SatELite preprocessor of MiniSat does not implement recent techniques. By using more advanced techniques, Coprocessor is able to reduce the redundancy in a formula further and improves the overall solving performance.
