点传递网络的匹配排除

Matching preclusion for vertex-transitive networks

Qiuli Li, Jinghua He, Heping Zhang

摘要:

在互连网络中,匹配排除是链路故障时鲁棒性的度量。设$G$是偶数阶图。匹配排除数$mp(G)$定义为删除导致没有完美匹配的子图的最小边数。许多互连网络是超匹配的,即它们的最优匹配排除集恰好是由单个顶点导出的。在本文中,我们得到了点传递图的一般结果,包括许多已知的网络。一个$k$ -正则连通点传递图具有匹配排除数$k$,且除六类图外都是超匹配的.由此可直接得到许多已有的结果,并导出了折叠$k$ -立方体、Hamming图和二等分$k$ -立方体等网络的匹配排除.

英文摘要:

In interconnection networks, matching preclusion is a measure of robustness when there is a link failure. Let $G$ be a graph of even order. The matching preclusion number $mp(G)$ is defined as the minimum number of edges whose deletion results in a subgraph without perfect matchings. Many interconnection networks are super matched, that is, their optimal matching preclusion sets are precisely those induced by a single vertex. In this paper, we obtain general results of vertex-transitive graphs including many known networks. A $k$-regular connected vertex-transitive graph has matching preclusion number $k$ and is super matched except for six classes of graphs. From this many previous results can be directly obtained and matching preclusion for some other networks, such as folded $k$-cubes, Hamming graphs and halved $k$-cubes, are derived.
