提出了含双参数的新共轭梯度法βk公式,证明了该方法在适当选取参数σ的强Wolfe线搜索下满足充分下降条件和全局收敛性.
提齣瞭含雙參數的新共軛梯度法βk公式,證明瞭該方法在適噹選取參數σ的彊Wolfe線搜索下滿足充分下降條件和全跼收斂性.

In this paper,we propose a new formula of the updateβk which has two parameters.And we show that the corresponding method satisfying the sufficient descent condition and global convergence with the strong Wolfe line search.
