摘要:

针对攻击代价相等时的有限资源网络毁伤问题, 给出了网络毁伤最大化的定义。为了改进近似求解算法求解毁伤最大化问题时复杂度较高的缺陷, 提出了基于拓扑势和CELF(cost-effective lazy-forward)的TPCELF(algorithm based on topology potential and CELF)算法。利用无标度网络和实测网络进行实验, 结果表明,TPCELF算法在计算速度上有较大的提升, 网络平均毁伤效果接近于近似求解算法; 且优于采用常见重要性度量指标排序算法得到的平均毁伤效果。所提方法可从网络毁伤的角度为复杂网络关键节点挖掘提供参考。

Abstract:

In view of the problem of network damage with limited resources when the attack cost is equal, the definition of network damage maximization is given. In order to improve the defect that the approximate algorithm suffers high computation complexity when solving network damage maximization problem, the algorithm based on topology potential and cost-effective lazy-forward (TPCELF) is proposed. Experiments with simulated scale-free networks and real network show that the TPCELF algorithm has a greater improvement in calculation speed, and the average damage effect of the network is close to the approximate algorithm. What's more, the TPCELF algorithm is better than other commonly used importance metric ranking algorithms in average network damage effect. The proposed approach can provide a reference for mining key nodes in complex networks from the perspective of network damage.

Key words: complex network, topology potential, damage maximization, cost-effective lazy-forward (CELF) algorithm
