    一个采用新重新开始策略的共轭梯度法

    A Conjugate Gradient Algorithm with a New Restart Strategy

      摘要
    • 摘要: 本文建立了共轭梯度法的一个新的重新开始策略,其特点是当目标函数进入二次区域后,它能从当前的两个共轭方向开始,逐次构造与这两个方向都共轭、而且又彼此共轭的搜索方向。本文最后讨论了相应算法对一般目标函数的收敛性质。

       

      Abstract: A new restart strategy for conjugate gradient method is established. In this strategy, starting from the two last conjugate directions obtained in previous circle, a set of conjugate directions is sequentially constructed when objective function enters quadratic region. The convergence of the corresponding algorithm is also discussed in this paper.
