冲突消解:一个基于决策文字和规则驱动的小句学习的一阶消解演算

Conflict Resolution: a First-Order Resolution Calculus with Decision Literals and Conflict-Driven Clause Learning

John Slaney, Bruno Woltzenlogel Paleo

摘要:

本文定义了(一阶)冲突解决演算:现代SAT求解器中使用的技术启发的决议演算的扩展。决议推理被限制为(一阶)单位传播和演算扩展的机制,假设决策文字和一个新的推理规则的子句学习,这是一个一阶推广的命题冲突驱动的子句学习(CDCL)过程。微积分是可靠的(因为它可以被自然演绎模拟)和反驳完备的(因为它可以模拟归结),这些事实在这里得到了详细的证明。

英文摘要:

This paper defines the (first-order) conflict resolution calculus: an extension of the resolution calculus inspired by techniques used in modern SAT-solvers. The resolution inference is restricted to (first-order) unit-propagation and the calculus is extended with a mechanism for assuming decision literals and a new inference rule for clause learning, which is a first-order generalization of the propositional conflict-driven clause learning (CDCL) procedure. The calculus is sound (because it can be simulated by natural deduction) and refutationally complete (because it can simulate resolution), and these facts are proven in detail here.
