Controllability and Directionality in Complex Networks

We investigate how to assign link directions in a given complex network to enhance its controllability. Based on the node residual degree, a method of assigning link direction is proposed. Numerical simulation demonstrates that the method outperforms the random direction assignment method in enhanci...

Zusammenfassung:We investigate how to assign link directions in a given complex network to enhance its controllability. Based on the node residual degree, a method of assigning link direction is proposed. Numerical simulation demonstrates that the method outperforms the random direction assignment method in enhancing the controllability of the network. Furthermore, robustness of control is also improved.
