两类无约束优化的充分下降共轭梯度法
Two Sufficient Descent Conjugate Gradient Methods for Unconstrained Optimization
摘要
Abstract
We proposed two sufficient descent conjugate gradient methods for unconstrained optimization. The sufficient descent direction is always obtained at each iteration. Under some suitable conditions, the global convergence can be induced. Numerical results show that these methods are feasible and effective.关键词
