Table 7.

C: robustness in importance of all nodes. D: robustness in the ranking of all nodes in importance. The DC column indicated the importance of the node defined by degree centrality (DC). The SPC column indicated the importance of the node defined by the Shannon-Parry centrality (SPC). For the robustness comparison, MIC had the best ranking in D and was ranked second in C. Actually, PCF was very unstable. In aspect D, PCF had poor performance. In the part of discussion, we will proceed to explain this phenomenon. Overall, compared with other methods, MIC had the best performance in robustness.
