关于(Omega-)正则模型检验

On (Omega-)Regular Model Checking

Axel Legay, Pierre Wolper

摘要:

检查无限状态系统通常通过将无限状态集编码为正则语言来完成。计算这样一个规则的表示,比如说,一个系统的可达状态集需要加速技术,可以计算无限数量的转换的效果。在已经提出的加速技术中,可以找到特定的和通用的技术。特定技术利用被分析的特定类型的系统,例如,操纵队列或整数的系统,而通用技术仅假设转换关系由有限状态转换器表示,其必须迭代。在本文中,我们调查的可能性,使用通用技术的情况下,只有特定的技术已被利用到目前为止。发现现有的通用技术往往是不适用的情况下,很容易处理的特定技术,我们已经开发出一种新的方法来迭代换能器。这种新方法建立在早期工作的基础上,但利用了许多新的概念和算法思想,通常在实验的帮助下诱导,这使其具有广泛的范围以及良好的性能。

英文摘要:

Checking infinite-state systems is frequently done by encoding infinite sets of states as regular languages. Computing such a regular representation of, say, the set of reachable states of a system requires acceleration techniques that can finitely compute the effect of an unbounded number of transitions. Among the acceleration techniques that have been proposed, one finds both specific and generic techniques. Specific techniques exploit the particular type of system being analyzed, e.g. a system manipulating queues or integers, whereas generic techniques only assume that the transition relation is represented by a finite-state transducer, which has to be iterated. In this paper, we investigate the possibility of using generic techniques in cases where only specific techniques have been exploited so far. Finding that existing generic techniques are often not applicable in cases easily handled by specific techniques, we have developed a new approach to iterating transducers. This new approach builds on earlier work, but exploits a number of new conceptual and algorithmic ideas, often induced with the help of experiments, that give it a broad scope, as well as good performances.
