Unidirectional and bidirectional links may coexist in many realistic networked complex
systems such as the city transportation networks. Even more, for some considerations …

Cascade phenomenon may lead to catastrophic disasters which extremely imperil the
network safety or security in various complex systems such as communication networks …

Many crucial real-world networks could be modeled as scale-free networks, which play an
important role in the human society. Once these functional network systems suffer from …

The robustness of complex networks against cascading failures has been of great interest,
while most of the researchers have considered undirected networks. However, to be more …

Taking into account the load, the load redistribution, and the node capacity, we study the
robustness of two interdependent networks A and B against cascading failures, where each …

In this paper, we propose several strategies for improving the robustness of scale-free
networks against cascading breakdown. Firstly, we introduce a damage-based measure of …

Recently, the study of optimizing network robustness has attracted increasing attentions, and
the constraint that every node's degree cannot be changed is considered. Although this …

The robustness of complex network is a core issue in complex network research. We agree
that not all overload nodes will be removed from the network in real networks because some …

Network robustness is a core problem in network researches, it has achieved many good
results by now. However, the network robustness against cascading failures under various …

Complex networks are often subjected to failure and attack. Recent work has addressed the
resilience of complex networks to either random or intentional deletion of nodes or links …
