一、引言利用计算机作网络、电路的最优化设计,人们已提出了不少的方法,但实用上仍存一些根本的目前尚处于前沿的问题。主要之一即如何尽量保证所得的结果属于“整体最优”,而非某种局部最优。可能得到局部最优结果常使工作者不能相信优化方法的效 I. INTRODUCTION The use of computers for network and circuit optimization design has been put forward many ways, but in practice there are still some fundamental issues that are still at the forefront. The main one is how to try to ensure that the results obtained belong to the “overall best” rather than some kind of local optimum. The possibility of obtaining local optimal results often leaves workers unable to believe the effectiveness of the optimization method
