- •
We propose a design strategy for the optimal control configurations of a directed network.
- •
We prove the optimality of the proposed design strategy.
- •
We find the dense and homogeneous networks have the larger controllability indexes.
- •
We find the average in-degree of the controlled state nodes is far less than that of the network.
