【关键词】Nonlinear programming Unconstrained optimization Trust region methods Approximate model Hybrid approach
【摘要】 In this paper, we propose a model-hybrid approach for nonlinear optimization that employs both trust region method and quasi-Newton method, which can avoid possibly resolve the trust region subproblem if the trial step is not acceptable. In particula...
