Cluster synchronization in community network with nonidentical nodes via intermittent pinning control*

A community network consists of 18 nodes with 3 communities. The top-left, top-right, and bottom are the first, second, and third communities respectively. The outer coupling matrix A is defined as: if nodes i and j  ( j ≠ i ) are connected by a solid line, then a ij = 1; if nodes i and j  ( j ≠ i ) are connected by a dashed line, then a ij = −1.
