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。
Gets or sets the minimum point size a user can select 获取或设置用户可选择的最小磅值。
Through multiple generation calculation , the minimum point of penalty function value was obtained , then the optimalc reduction distribution was found 通过粒子群多代运算,求出罚函数值最小点,得到压下负荷最佳分配点。
And we put forward a new algorithm that can solve the drawback of back propagation that easily converge to a local minimum point of the error function 而后针对bp算法易陷入局部极小的缺陷,提出了一种新的算法ambp算法。
Since it adopt the steepest descent method in nonlinear programming , it has the drawback that easy converge to a local minimum point of the error function 由于它采用非线性规划中的最速下降法,因而存在极易陷入局部极小的缺陷。
