解信赖域子问题的混合折线法

The Hybrid Dogleg Method to Solve Subproblems of Trust Region

基于Powell的单折线法 ,Dennis的双折线法和赵英良的切线单折线法 ,提出了解信赖域子问题的一种混合折线算法 ,并给出了数值试验结果 .

Based on the Powell′s single dogleg method,Dennis′ double dogleg mothod and Zhao Yingliang′s tagent single dogleg method,this paper presents a hybrid dogleg method to solve the subproblem of trust region and the results of numerical experiments.
