通信下推系统的可达性分析

Reachability Analysis of Communicating Pushdown Systems

Alexander Heussner, Jérôme Leroux, Anca Muscholl, Grégoire Sutre

摘要:

在可靠的FIFO通道上异步通信的递归程序的可达性分析要求限制以确保可判定性。我们的第一个结果描述了通信拓扑结构的可判定可达性问题,仅限于急切运行(即,消息在发送后立即被接收或从未被接收的情况下运行)。在可判定的情况下,问题是EXPTIME完全的。第二个结果是一个双指数时间算法的有界上下文分析在这种情况下,以及匹配的下限。这两个结果扩展和改进以前的工作从La Torre等人。

英文摘要:

The reachability analysis of recursive programs that communicate asynchronously over reliable FIFO channels calls for restrictions to ensure decidability. Our first result characterizes communication topologies with a decidable reachability problem restricted to eager runs (i.e., runs where messages are either received immediately after being sent, or never received). The problem is EXPTIME-complete in the decidable case. The second result is a doubly exponential time algorithm for bounded context analysis in this setting, together with a matching lower bound. Both results extend and improve previous work from La Torre et al.
