Global Convergence of DY Conjugate Gradient Method under a New Line Search
Author(s): 
Pages: 34-38
Year: Issue:  1
Journal: Guangxi Sciences

Keyword:  无约束优化共轭梯度法Wolfe线搜索全局收敛性;
Abstract: 给出一种求解无约束优化问题的新线搜索,证明由新线搜索和DY公式产生的算法具有全局收敛性,再对此算法进行数值试验,并将其数值结果与Wolfe线搜索下PRP方法、DY方法以及另外几种线搜索下DY共轭梯度法的数值结果进行比较来验证新算法是有效的.
