论文摘要
我们表明,对于扁平的有损通道机,即控制图中没有嵌套周期,可及性,重复达到性能,不终端和无界度对于有损耗的通道机而言。上部复杂性结合依赖于对有损通道动作的迭代的精细分析,并使用压缩单词技术进行有效的推理,并具有指数长度的路径。下限已经适用于无环或单路径机。
We show that reachability, repeated reachability, nontermination and unboundedness are NP-complete for Lossy Channel Machines that are flat, i.e., with no nested cycles in the control graph. The upper complexity bound relies on a fine analysis of iterations of lossy channel actions and uses compressed word techniques for efficiently reasoning with paths of exponential lengths. The lower bounds already apply to acyclic or single-path machines.
