| Abstract(in English) | Many real world networks such as power grid and communication networks are commonly scale-free, but highly vulnerable against malicious attacks. However, onion-like networks with positive degree-degree correlations are known as optimal robust structures against attacks. On the other hand, we remark a relation between network robustness and loops since a network with higher degree-degree correlations does not always have higher robustness. In this study, we aim to improve the robustness of connectivity from the perspective of loop enhancement. We propose new rewirings for enhancing loops by using Feedback Vertex Set (FVS) and apply them to empirical networks in computer simulations. Our result shows a strong correlation between the robustness and the size of FVS, and suggests that loop enhancement is essential for improving robustness. |
