摘要
文〔1〕介绍了一类带精确线搜索的下降算法并用此算法统一处理了最速下降法,共轭梯度法等的收敛性。本文在四种非精确线搜索下讨论了一类比〔1〕广的特殊算法,并获得了算法较强的收敛性质。
A class of descent algorithms with exact line search were introduced in[1], and by them the convergences of the steepest descent method and the conjugate gradient method etc are treated in a unified way. In this paper, we discuss a class of special method which contain [1] and obtain the convergence properties of strongr algorithm under four nonexact line searchs.
