Dynamics of k-core percolation

C. L. Farrow, P. Shukla, P. M. Duxbury

摘要:

在许多网络应用中,节点是稳定的,只要它们至少有k个邻居,并且k稳定节点的网络被称为k核。随机攻击的脆弱性的特点是随机选择的k-核心节点被删除后发生的剔除雪崩的大小。在二维,三维和四维的晶格,以及小世界网络的模拟表明,幂律雪崩发生在一阶k-核心系统,而截断雪崩的特点是二阶的情况下。

英文摘要:

In many network applications nodes are stable provided they have at least k neighbors, and a network of k-stable nodes is called a k-core. The vulnerability to random attack is characterized by the size of culling avalanches which occur after a randomly chosen k-core node is removed. Simulations of lattices in two, three and four dimensions, as well as small world networks, indicate that power-law avalanches occur in first order k-core systems, while truncated avalanches are characteristic of second order cases.
