在wolfe步长搜索下,对解无约束最优化问题的共轭梯度法的迭代参数做出改进,扩大了它的选取范围,并在目标函数可微的条件下,证明了算法的全局收敛性.
This paper presents a new conj sing Wolfe inexact line search and extending ugate gradient method for unconstrained optimization problem by u- the range of the iterative parajueter. Global convergence of such a method is proved under the condition that the objective function is continuously differentiable.
