用树自动机判定归纳分离逻辑的蕴涵

Deciding Entailments in Inductive Separation Logic with Tree Automata

Radu Iosif, Adam Rogalewicz, Tomas Vojnar

摘要:

具有归纳定义的分离逻辑(SL)是用于指定复杂递归数据结构的自然形式主义,用于操作此类结构的程序的组合验证。任何基于SL的自动验证过程的关键要素是蕴涵问题的可判定性。在这项工作中,我们减少了蕴涵问题的一个非平凡的子集SL描述树(和超越)的语言包含树自动机(TA)。我们的减少提供了严格的复杂性界限的问题,并表明在我们的片段的蕴涵是EXPTIME完成。出于实用的目的,我们利用自动机理论的最新进展,如包含检查非确定性TA避免明确的确定性。我们实现了我们的方法,并提出了有前途的初步实验结果。

英文摘要:

Separation Logic (SL) with inductive definitions is a natural formalism for specifying complex recursive data structures, used in compositional verification of programs manipulating such structures. The key ingredient of any automated verification procedure based on SL is the decidability of the entailment problem. In this work, we reduce the entailment problem for a non-trivial subset of SL describing trees (and beyond) to the language inclusion of tree automata (TA). Our reduction provides tight complexity bounds for the problem and shows that entailment in our fragment is EXPTIME-complete. For practical purposes, we leverage from recent advances in automata theory, such as inclusion checking for non-deterministic TA avoiding explicit determinization. We implemented our method and present promising preliminary experimental results.
