In chapter 3 , by minimizing a quadratic model restricting next search direction to a subset of span { - g _ ( k ) , d _ ( k - 1 ) } , we propose other formula of parameter ~ ( * ) k convergences of the new method and its hybrid formula are proved under monotone line search . their numerical results show that they are efficient
在第三章中，通过最小化一个限制下次搜索方向在span { - g _ k ， d _ ( k - 1 ) }子集上的二次模型，我们提出了_ k ~ *取新形式或其杂交形式的共轭梯度法是有效的。
