| 摘 要： | 基于拟牛顿法中MBFGS修正技术，对HS共轭梯度法中搜索方向的计算公式进行了修正，在较弱的条件下，结合非单调Armijo线性搜索技术，证明了所提出的修正HS共轭梯度法具有全局收敛性，最后通过数值实验验证了所提出的算法的有效性。

| Abstract: | In this thesis, based on the MBFGS update technique, we firstly modify the calculation formula of the search direction in the HS conjugate gradient method. Under mild conditions, we prove the global convergence of the proposed modified HS conjugate gradient method with the nonmonotonie Armijo line search. Finally, the numerical results show that the proposed method is effective. |
