Based on the two-level “Master-Slave” mode, a new introduced “Master-subMaster-Slave” structure is better than the “Master-Slave” structure in parallel.
It is difficult to achieve the synchronization for the master-slave chaotic systems with nonidentical parameters,so the uniform synchronization with a small error bound is discussed.
I am absolutely in favor of liberation-liberation for both man and woman-because it is a simple law: the enslaver also becomes a slave of his own slaves.
