摘要:

我们发现,真正的多重网络是出乎意料的强大,对有针对性的攻击高度节点,隐藏层间几何相关性预测这种鲁棒性。如果没有几何相关性,多重显示出一个突然的故障的相互连接,即使与层间的程度相关性。与几何相关性,我们反而观察到一个多步级联过程导致一个连续的过渡,这显然成为完全连续的热力学极限。我们的研究结果是重要的设计有效的保护策略和强大的互动网络在许多领域。

英文摘要:

We show that real multiplex networks are unexpectedly robust against targeted attacks on high degree nodes, and that hidden interlayer geometric correlations predict this robustness. Without geometric correlations, multiplexes exhibit an abrupt breakdown of mutual connectivity, even with interlayer degree correlations. With geometric correlations, we instead observe a multistep cascading process leading into a continuous transition, which apparently becomes fully continuous in the thermodynamic limit. Our results are important for the design of efficient protection strategies and of robust interacting networks in many domains.
