摘要
提出了一种新的在Glodstein线搜索准则下的修正Conjugate Descent方法,该修正方法不需要其他要求即可满足充分下降条件,同时,证明了该方法在某些弱条件下的收敛性.
This paper presents search principle, which can satisfy a kind of new modified Conjugate Descent Method under sufficient descent condition without other requirements, and the convergence of this method under some weak conditions
