我们证明,如果具有 n 个节点的连通图具有电导 &phis;然后谣言传播,也称为随机广播,使用推拉策略以高概率在 O(log4 n/&phis;6) 步内成功广播消息。我们的方法的一个有趣的特点是,它在谣言传播和 Spielman 和 Teng 的光谱稀疏化过程之间建立了联系 [23]。
We show that if a connected graph with n nodes has conductance &phis; then rumour spreading, also known as randomized broadcast, successfully broadcasts a message within O(log4 n/&phis;6) many steps, with high probability, using the PUSH-PULL strategy. An interesting feature of our approach is that it draws a connection between rumour spreading and the spectral sparsification procedure of Spielman and Teng [23].
