Controllability and Optimization of Complex Networks Based on Bridges

Lifu Wang, Guotao Zhao, Zhi Kong, Yunkang Zhao, Hocine Cherifi
2020 Complexity  
Bridges are a kind of key edges whose removal will disconnect a network and increase connected components. Here, we investigate the effects of removing bridges on controllability of network.  ...  In a complex network, each edge has different functions on controllability of the whole network. A network may be out of control due to failure or attack of some specific edges.  ...  ), . . . , x N (t)) T is the state of nodes in complex network, x j (t) is the state of node j at time t; A ∈ R N×N is the adjacency matrix of complex network, where a ij � 0 means that there is no connection  ...
