AI总结:

本文研究计数模理论(#SMT)的知识编译问题,提出基于穷举DPLL(T)搜索轨迹的自顶向下编译策略,以高效获得支持计数的表示形式。

摘要:

当输入公式处于确定性可分解否定范式(d-DNNF)时,命题模型计数(#SAT)可以被高效求解。将任意公式转换为一种能够高效执行计数等推理任务的表示形式,称为知识编译。自顶向下知识编译是解决#SAT问题的一种最先进技术,它利用穷举DPLL搜索的轨迹来获得d-DNNF表示。虽然知识编译在命题方法中已得到充分研究,但针对(无量词)计数模理论设置(#SMT)的知识编译研究程度要低得多。在本文中,我们讨论#SMT的编译策略。我们特别提倡一种基于穷举DPLL(T)搜索轨迹的自顶向下编译器。

英文摘要:

Propositional model counting (#SAT) can be solved efficiently when the input formula is in deterministic decomposable negation normal form (d-DNNF). Translating an arbitrary formula into a representation that allows inference tasks, such as counting, to be performed efficiently, is called knowledge compilation. Top-down knowledge compilation is a state-of-the-art technique for solving #SAT problems that leverages the traces of exhaustive DPLL search to obtain d-DNNF representations. While knowledge compilation is well studied for propositional approaches, knowledge compilation for the (quantifier free) counting modulo theory setting (#SMT) has been studied to a much lesser degree. In this paper, we discuss compilation strategies for #SMT. We specifically advocate for a top-down compiler based on the traces of exhaustive DPLL(T) search.
