- Abstract:
-
Optimizing network controllability continues to be a research hotspot in network science. Based on the PBH criterion, in this paper, we introduce the computation method of minimum control input and the quantitative analysis index of network controllability. We classify the row correlations of the matrix λkI-A and confirm the relationship between eigenvalue 0/-1 and the row repetition correlation as well as the row correlation of matrix λkI-A. We describe two kinds of 0/-1 regularity structures, isolated and connected link structures. Using the method for eliminating these two kinds of regularity structures, we then propose the basic step of structure optimization. Through experimental analysis, we verify that the eigenvalue 0/-1 could greatly influence network controllability, and that structural optimization could improve network controllability. These results not only demonstrate the importance of eigenvalue 0/-1 and the effectiveness of optimizing controllability, but also provide a new method and concept for network controllability research.
