论文摘要
网络鲁棒性的深入研究概念之一是$ r $ bobustness,它是由整数$ r $量化的网络拓扑属性。平均分子降低(MSR)算法及其变体需要达到弹性共识。但是,确定$ r $ - 塑料对于大型网络是棘手的。在本文中,我们提出了一种基于样本的算法,以大约测试带有$ n $ Vertices和$ m $边缘的Digraph的$ r $ bobustness。对于在最小值内进行中等假设的DIGRAPH和错误参数$ 0 <ε\ leq 1 $,建议的算法将$(r+εn)$区分出与不是$ r $ -Robust的图形的强大图形,而不是$ r $ -Robust,则具有概率$(1-δ)$。我们的算法在$ \ exp中运行(o(((\ ln {\ frac {1} {εδ}}})/ε^2))\ cdot m $ time。如果$ε$是一个常数,则运行时间是线性的。
One of the intensely studied concepts of network robustness is $r$-robustness, which is a network topology property quantified by an integer $r$. It is required by mean subsequence reduced (MSR) algorithms and their variants to achieve resilient consensus. However, determining $r$-robustness is intractable for large networks. In this paper, we propose a sample-based algorithm to approximately test $r$-robustness of a digraph with $n$ vertices and $m$ edges. For a digraph with a moderate assumption on the minimum in-degree, and an error parameter $0<ε\leq 1$, the proposed algorithm distinguishes $(r+εn)$-robust graphs from graphs which are not $r$-robust with probability $(1-δ)$. Our algorithm runs in $\exp(O((\ln{\frac{1}{εδ}})/ε^2))\cdot m$ time. The running time is linear in the number of edges if $ε$ is a constant.
