概率时间自动机的最小见证人

Minimal witnesses for probabilistic timed automata

Simon Jantsch, Florian Funke, Christel Baier

摘要:

见证子系统在概率系统的分析中被证明是一个有用的概念,例如作为关于为什么给定属性成立的诊断信息或作为细化算法的输入。介绍了概率时间自动机(PTA)中可达性问题的见证子系统。使用一个新的操作差界矩阵,它示出了如何法卡斯证书的有限状态互模拟子系统的PTA可以被翻译成见证子系统。我们提出了算法的最小见证子系统的三个概念下的最小性,从不同的角度捕捉的时间行为的计算,并讨论了它们的复杂性。

英文摘要:

Witnessing subsystems have proven to be a useful concept in the analysis of probabilistic systems, for example as diagnostic information on why a given property holds or as input to refinement algorithms. This paper introduces witnessing subsystems for reachability problems in probabilistic timed automata (PTA). Using a new operation on difference bounds matrices, it is shown how Farkas certificates of finite-state bisimulation quotients of a PTA can be translated into witnessing subsystems. We present algorithms for the computation of minimal witnessing subsystems under three notions of minimality, which capture the timed behavior from different perspectives, and discuss their complexity.
