AI总结:

针对逻辑系统可达性分析的维数灾难与多项式逻辑zonotope交集不封闭问题,提出约束多项式逻辑zonotope方法,兼顾计算效率与精确交集能力,经实证验证了其优势。

摘要:

本文提出了基于约束多项式逻辑zonotope的可达性分析方法。我们开展可达性分析以计算所有可能到达的状态集合。为此,我们采用了近期提出的一种集合表示方法——多项式逻辑zonotope,用于对逻辑系统进行计算高效且精确的可达性分析。值得注意的是,多项式逻辑zonotope能够解决逻辑系统可达性分析中的“维数灾难”问题,因为该集合表示方法仅需使用h个生成元即可表示2^h个二进制向量。完成可达性分析后,形式化验证环节需要检验计算得到的可达集与不安全集的交集是否为空。由于多项式逻辑zonotope不具备交集封闭性,我们提出了约束多项式逻辑zonotope的构造形式,它既保留了多项式逻辑zonotope在可达性分析中的计算效率与精确性,又能够实现精确的交集运算。此外,本文还开展了大量实证研究,以证明并验证约束多项式逻辑zonotope的优势。

英文摘要:

In this paper, we propose reachability analysis using constrained polynomial logical zonotopes. We perform reachability analysis to compute the set of states that could be reached. To do this, we utilize a recently introduced set representation called polynomial logical zonotopes for performing computationally efficient and exact reachability analysis on logical systems. Notably, polynomial logical zonotopes address the "curse of dimensionality" when analyzing the reachability of logical systems since the set representation can represent $2^h$ binary vectors using $h$ generators. After finishing the reachability analysis, the formal verification involves verifying whether the intersection of the calculated reachable set and the unsafe set is empty or not. Polynomial logical zonotopes lack closure under intersections, prompting the formulation of constrained polynomial logical zonotopes, which preserve the computational efficiency and exactness of polynomial logical zonotopes for reachability analysis while enabling exact intersections. Additionally, an extensive empirical study is presented to demonstrate and validate the advantages of constrained polynomial logical zonotopes.
