有限迹上的一阶时态逻辑:语义性质、可判定片段及其应用

First-order Temporal Logic on Finite Traces: Semantic Properties, Decidable Fragments, and Applications

Alessandro Artale, Andrea Mazzullo, Ana Ozaki

摘要:

基于有限严格线性顺序的时态逻辑的形式主义,在文献中称为有限迹,已被用于自动规划,过程建模,(运行时)验证和程序合成中的时态规范,以及知识表示和推理。本文主要研究有限迹上的一阶时态逻辑。我们首先调查保存有限和无限的痕迹之间的公式的等价性和可满足性,通过提供一组语义和句法条件,以保证在这两种情况下推理之间的区别可以模糊。此外,我们表明,满足性问题的有限迹几个可判定的片段的一阶时序逻辑是ExpSpace完全的,在无限迹的情况下,而它减少到NExpTime有限迹有界的时刻数被认为是。这也导致了新的复杂性结果的时间描述逻辑在有限的痕迹。最后,我们调查应用程序的规划和验证,特别是通过建立连接的概念不敏感的无限性和安全性的文献。

英文摘要:

Formalisms based on temporal logics interpreted over finite strict linear orders, known in the literature as finite traces, have been used for temporal specification in automated planning, process modelling, (runtime) verification and synthesis of programs, as well as in knowledge representation and reasoning. In this paper, we focus on first-order temporal logic on finite traces. We first investigate preservation of equivalences and satisfiability of formulas between finite and infinite traces, by providing a set of semantic and syntactic conditions to guarantee when the distinction between reasoning in the two cases can be blurred. Moreover, we show that the satisfiability problem on finite traces for several decidable fragments of first-order temporal logic is ExpSpace-complete, as in the infinite trace case, while it decreases to NExpTime when finite traces bounded in the number of instants are considered. This leads also to new complexity results for temporal description logics over finite traces. Finally, we investigate applications to planning and verification, in particular by establishing connections with the notions of insensitivity to infiniteness and safety from the literature.
