Introduction The function and performance of complex networks rely on their robustness. Due to its broad applications, the attack robustness of complex networks has received growing attention.

Introduction The ultimate purpose of research on network robustness is to obtain a robust network. Many studies have been devoted to designing networks with optimal robustness 。 However, most real networks are the results of complex and extended processes; thus, designing new ones is almost impossible. Therefore, explore existing networks and improving their robustness by modifying the topology, e.g., adding, deleting, rewiring, or repairing edges, seem more feasible and effective.

Introduction Rather than modifying the network structure, an alternative approach is to change the information of the network structure.
