A stationary point which is neither a local maximum nor a local minimum point is called a saddle point. 一个既不是局部极大点又不是局部极小点的平稳点称为一个鞍点。
Aiming at the local minimum possibly emerged in the motion procedure, an escape method has been proposed. 针对人工势场方案可能出现的局部极小问题提出了逃逸方法。
We analyzed various improved methods because of the problem that conventional BP algorithm was liable to trap in local minimum value and was slow rate of convergence. 针对传统即算法易陷入局部极小和收敛速度慢的问题,分析了各种改进方法。
It pays a worker the salary that is lower than the local minimum salary; 低于当地最低工资标准支付劳动者工资的;
Combined with the gradient search, a hybrid genetic algorithm is formed to overcome the local minimum of the gradient search and the slowness of convergence rate of simple genetic algorithms. 同时,将遗传算法与梯度优化方法相结合,使得混合型遗传算法有效地解决了梯度算法局部极小问题和简单遗传算法的收敛速度慢问题。
