我们提出了简单的确定性算法的子图发现和枚举的广播CONGEST模型的分布式计算: 对于任何常数$k$,检测$k $路径和$k$节点上的树可以在$O(1)$轮内完成。 对于任何常数$k$,检测$k$-循环和$k$节点上的伪树可以在$O(n)$轮中完成。 --在$d$-退化图上,团和$4$-圈可以在$O(d + log n)$轮中枚举,而$5$-圈可以在$O(d^2 + log n)$轮中枚举。 在许多情况下,这些界限紧到对数因子。此外,我们证明了$d$-退化图的算法可以改进到最佳复杂度$O(d/log n)$和$O(d^2/log n)$,分别在支持的CONGEST模型,它可以被看作是一个中间模型之间的CONGEST和拥塞团。
We present simple deterministic algorithms for subgraph finding and enumeration in the broadcast CONGEST model of distributed computation: -- For any constant $k$, detecting $k$-paths and trees on $k$ nodes can be done in $O(1)$ rounds. -- For any constant $k$, detecting $k$-cycles and pseudotrees on $k$ nodes can be done in $O(n)$ rounds. -- On $d$-degenerate graphs, cliques and $4$-cycles can be enumerated in $O(d + log n)$ rounds, and $5$-cycles in $O(d^2 + log n)$ rounds. In many cases, these bounds are tight up to logarithmic factors. Moreover, we show that the algorithms for $d$-degenerate graphs can be improved to optimal complexity $O(d/log n)$ and $O(d^2/log n)$, respectively, in the supported CONGEST model, which can be seen as an intermediate model between CONGEST and the congested clique.
