一类无充分下降条件的非单调共轭梯度法的全局收敛性分析

摘要

In [3] Liu et al. investigated global convergence of conjugate gradient methods.In that paper they allowed βk to be selected in a wider range and the global convergence of the corresponding algorithm without sufficient decrease condition was proved. This paperinvestigates global convergence of nonmonotone conjugate gradient method under the same conditions.
