Cascading failures in many systems such as infrastructures or financial networks can lead to catastrophic system collapse. We develop here an intuitive, powerful and simple-to-implement approach for mitigation of cascading failures on complex networks based on local network structure. We offer an algorithm to select critical nodes, the protection of which ensures better survival of the network. We demonstrate the strength of our approach compared to various standard mitigation techniques. We show the efficacy of our method on various network structures and failure mechanisms, and finally demonstrate its merit on an example of a real network of financial holdings.
在基础设施或金融网络等许多系统中，级联故障可能导致灾难性的系统崩溃。我们在这里开发了一种基于局部网络结构的直观、强大且易于实现的复杂网络级联故障缓解方法。我们提供了一种选择关键节点的算法，保护这些节点可以确保网络更好地生存。我们比较了各种标准缓解技术，展示了我们方法的优势。我们在各种网络结构和故障机制上展示了我们方法的有效性，并最终在金融控股的真实网络示例上展示了其优点。
