Abstract

With tableaux-based reasoning approaches or model checking techniques for propositional linear-time temporal logics, PLTL, it is easily possible to construct counter examples for formulae that are not valid. In contrast, only the information that a formula is satisfiable is usually available in resolution-based inference systems. In this paper we present a resolution-based approach for constructing models for satisfiable PLTL formulae. Our approach is based on using the standard model construction for sets of propositional clauses saturated under ordered resolution in the different time points of a temporal model. The temporal model construction procedure is also designed in such a way that it can be easily implemented in existing theorem rovers for PLTL.
基于分辨率的PLTL模型构建
使用基于表格的推理方法或命题线性-时间-时间逻辑(PLTL)的模型检查技术,很容易为无效的公式构建反例。相反,在基于分辨率的推理系统中,通常只有公式是可满足的信息。本文提出了一种基于分辨率的方法来构造可满足PLTL公式的模型。我们的方法是基于对在时间模型的不同时间点的有序分辨率下饱和的命题子句集使用标准模型构建。同时,本文还设计了时间模型的构建过程,使其易于在现有的PLTL定理探测车中实现。
