“…When the synchronization of dynamical networks does not appear under some appropriate node dynamics and topological structures, many controlling (e. g., the adaptive and pinning control) methods have been designed to achieve synchronization [12,23,25,26,28] and many references cited therein. When the control is employed for every node DOI: 10.14736/kyb-2016- in realizing the synchronization, it would take a great cost.…”
