Enhancing Complex Network Controllability by Rewiring Links

We propose a method to enhance controllability of directed network by rewiring links while keeping the total number of links unchanged. Numerical simulation on two canonical network models (ER and SF) demonstrates that this method is effective. We show that the improved controllability is mainly det...

Description
Summary:We propose a method to enhance controllability of directed network by rewiring links while keeping the total number of links unchanged. Numerical simulation on two canonical network models (ER and SF) demonstrates that this method is effective. We show that the improved controllability is mainly determined by the mean degree and does not depend on the initial degree distribution and the size of network. Furthermore, we discuss the correlation between controllability and heterogeneity.
