在这笔记,由把 PR 和 HS 方法的好数字表演与 FR 方法的全球集中性质相结合,新重启的一个班三项条款结合坡度方法被介绍。有二种普通的线搜索的新方法的全球集中性质被证明。
In this note,by combining the nice numerical performance of PR and HS methods with the global convergence property of FR method,a class of new restarting three terms conjugate gradient methods is presented.Global convergence properties of the new method with two kinds of common line searches are proved.
