互联网络中的传播动力学优化

Optimizing spreading dynamics in interconnected networks

Liming Pan, Wei Wang, Shimin Cai, Tao Zhou

摘要:

在互连网络的层之间添加边是优化传播动力学的重要方法。虽然以前的研究大多集中在添加一个边缘的情况下,添加多个边缘的理论上的最优策略仍然需要研究。在本研究中,我们基于易感染-易感染(SIS)模型,研究了互联网络中最大化平稳传播流行率的问题。对于两个孤立的网络,我们通过选择多个互连边来最大化临界点附近的传播流行率。我们提出了一个理论分析的基础上的离散时间马尔可夫链的方法来获得近似的最优策略。该策略预测的最佳层间结构使互联网络的传播流行率最大化,同时使传播爆发阈值最小化。在合成网络和真实网络上的数值模拟表明,在临界点附近,该策略比连接大度节点和随机连接具有更好的性能。

英文摘要:

Adding edges between layers of interconnected networks is an important way to optimize the spreading dynamics. While previous studies mostly focus on the case of adding a single edge, the theoretical optimal strategy for adding multiple edges still need to be studied. In this study, based on the susceptible-infected-susceptible (SIS) model, we investigate the problem of maximizing the stationary spreading prevalence in interconnected networks. For two isolated networks, we maximize the spreading prevalence near the critical point by choosing multiple interconnecting edges. We present a theoretical analysis based on the discrete-time Markov chain approach to derive the approximate optimal strategy. The optimal inter-layer structure predicted by the strategy maximizes the spreading prevalence, meanwhile minimizes the spreading outbreak threshold for the interconnected network simultaneously. Numerical simulations on synthetic and real-world networks show that near the critical point, the proposed strategy gives better performance than connecting large degree nodes and randomly connecting.
