But it has some disadvantages, for example:the rate of evolutional learning is too slow sometimes, and the stability of network is discontented.
演化学习具有全局优化性能好,实验样本数要求少等优点,但也存在一些问题,如演化学习的速度较慢、模型的稳定性较差等。
How to test that the stability of network social ecosystem has been achieved, or how to make the network society reaches a steady state, is now an important subject to study for us.
如何检验网络社会生态系统是否已经达到稳定,或者如何使网络社会达到稳定状态,这就是我们现在所要研究的一个重要课题。
When exciting Sin voltage source is applied to proper port, the stability of network depends on the sign of active and reactive components for fundamental-wave current entering port of networks.
若在适当端口施加正弦电压源,则网络的稳定性取决于进入端口基波电流的实功与虚功成份的符号值。
