一类无约束优化的修正共轭梯度法
A Modified Conj ugate Gradient Method for Unconstrained Optimization
摘要
Abstract
A modified conj ugate gradient method for unconstrained optimization was proposed.The direction is sufficient descent at each iteration.Under some suitable conditions,the method is global convergence.Numerical results show that these methods are feasible and effective.关键词
