摘 要:
本文就非拟牛顿法在无约束最优化问题上,对采用非单调线搜索的情况下是否具有全局收敛性进行了研究,在目标函数满足一致凸的条件下,证明了非拟牛顿族是全局收敛的.[著者文摘]

Abstract:
The non-quasi-Newton method for unconstrained optimization is investigated. Non-monotone line search procedure is introduced, which is combined with the non-quasiNewton family. Under the uniformly convexity assumption on objective function,the global convergence of the non-Quasi-Newton family is proved.[著者文摘]
