中文摘要：

非线性共轭梯度法是解决大规模优化问题的一种非常有效的方法,提出了一个修正的PRP方法,该参数带有干扰因子,并证明了这一新的参数具有非负性,且在适当条件下,采用Wolfe线搜索,证明该算法具有全局收敛性.

英文摘要：

The nonlinear conjugate gradient method is a very effective iterative method for solving large-scale optimal problems.In this paper,a modified PRP conjugate gradient method with disturbance factor is proposed and non-negative property of the formula is proved. Under suitable conditions,the global convergence of the algorithm with the Wolfe line search is discussed.
