“…Specifically, synchronization, as an important and interesting collective behavior of complex networks in our real life, has drawn increasing attention from different fields such as information science, biological system, image processing, secure communication, etc [9][10][11][12][13][14][15]. Up to now, there are many widely-studied synchronization schemes, which defines the correlated in-time behaviors among the nodes in a dynamical network, such as complete synchronization [16], phase synchronization [17], generalized synchronization [18], projective synchronization [19,20], lag synchronization [21], cluster synchronization [22], synchronization in multi-agent systems [23,24]. The synchronization observed in a network is usually called "inner synchronization" as it is a collective behavior within this network.…”
