摘要 提出一类求解大规模无约束最优化问题的新共轭梯度方法.该方法在任何线性搜索下都具有充分下降性,并证明了采用Wofle线性搜索时其全局收敛性.数值实验表明该方法是很有效的. In this paper,we propose a new nonlinear conjugate gradient method for large-scale unconstrain optimization which possesses the sufficient descent property without any line searches.Global convergence of this method is proved with wofle line search.Preliminary numerical results show that this method is very efficient.
