研究了边的失效对无标度网络拓扑结构的影响.在去边机制下,对BA网络进行4种攻击模拟;对不同边失效概率P和被攻击节点数百分比f,计算网络全局效率E,并给出E-f关系图和E-P关系图;通过数据分析,得出适合4种攻击模式的最佳攻击策略.%Four kinds of attacks on the BA network were investigated, the values of E were calculated under some given P (the probability of removing an edge) and f (the fraction of nodes attacked).By the simulations and analysis of the data, the optimal strategy for four kinds of attacks was obtained respectively.
