求解信赖域子问题的Newton-GMRES方法
Newton-GMRES Method for Solving Trust Region Subproblems
摘要
Abstract
In order to solve the trust region subproblem Newton-GMRES algorithm was constructed with a new smooth approximation function,complementary model of sub-problem was converted into an equivalent system of equations.The inexact Newton meth-od was combined with the GMRES algorithm to obtain the Newton-GMRES algorithm for solving trust region subproblems.The convergence and well-posedness of the algorithm was proved under certain conditions.Numerical experimental results show that the algo-rithm is practicable and effective.关键词
