一种新线搜索下DY共轭梯度法的全局收敛性
Global Convergence of DY Conjugate Gradient Method under a New Line Search
摘要
Abstract
A new line search is proposed for solving the unconstrained optimization problem.The global convergence of the new conjugate gradient algorithm, which is generated by this line search and DY conjugate gradient formula, is obtained. Further, by testing the new algorithm and comparing its numerical results with those of PRP and DY methods under WWP line search, and with those of DY methods under other line searches, the results show that this new algorithm is effective.关键词
