摘要

摘要 核心-外围结构常见于各种现实世界的网络中,根据连接模式将节点分为核心节点和外围节点。它在确保网络潜在功能和内在秩序方面发挥着重要作用。网络不可避免地会受到恶意攻击和随机误差的影响,这可能会导致核心-外围结构崩溃,进而导致性能下降,甚至网络行为完全不稳定。因此,如何在这种结构被破坏后迅速恢复具有重要意义。然而,现有关于网络的研究很少关注核心-外围结构的恢复。在此,我们提出了一种新颖的恢复指数,用于描述和衡量灾难发生时核心-外围恢复的质量。考虑到中尺度核心-外围结构和全局网络连通性,我们设计了几种以我们的指数为指导的高效算法,以提供最优或接近最优的恢复计划。数值结果证明了我们的框架能显著提高核心-外围修复的效率。

Restoring core-periphery structure of networks
Abstract Core-periphery structure is commonly observed in diverse real-world networks, where nodes are categorized as core or peripheral nodes by connection patterns. It plays an important role in ensuring potential functionality and intrinsic order in networks. Networks are inevitably suffering from the malicious attacks and random errors, which could lead to the collapse of core-periphery structure, and in turn the performance degradation and even the total instability of network behaviors. Therefore, it is of great significance to rapidly recover such structure after destruction. However, few of the existing work about network have laid emphasis on core-periphery restoration. Here we propose a novel recovery index to characterize and measure the quality for the core-periphery restoration when a disaster happens. Several efficient algorithms guided by our index are devised to provide optimal or near-optimal restoration plans considering both the mesoscale core-periphery structure and global network connectivity. Numerical results are provided to demonstrate the efficacy of our framework that remarkably enhances core-periphery restoration.

期刊介绍: General physics – physics of elementary particles and fields – nuclear physics – atomic, molecular and optical physics – classical areas of phenomenology – physics of gases, plasmas and electrical discharges – condensed matter – cross-disciplinary physics and related areas of science and technology. Letters submitted to EPL should contain new results, ideas, concepts, experimental methods, theoretical treatments, including those with application potential and be of broad interest and importance to one or several sections of the physics community. The presentation should satisfy the specialist, yet remain understandable to the researchers in other fields through a suitable, clearly written introduction and conclusion (if appropriate). EPL also publishes Comments on Letters previously published in the Journal.
