متن کاملA Trust-Region-Based BFGS Method with Line Search Technique for Symmetric Nonlinear Equations
A trust-region-based BFGS method is proposed for solving symmetric nonlinear equations. In this given algorithm, if the trial step is unsuccessful, the linesearch technique will be used instead of repeatedly solving the subproblem of the normal trust-region method. We establish the global and superlinear convergence of the method under suitable conditions. Numerical results show that the given ...
متن کاملA new backtracking inexact BFGS method for symmetric nonlinear equations
A BFGS method, in association with a new backtracking line search technique, is presented for solving symmetric nonlinear equations. The global and superlinear convergences of the given method are established under mild conditions. Preliminary numerical results show that the proposed method is better than the normal technique for the given problems. c © 2007 Elsevier Ltd. All rights reserved.
متن کاملA Trust Region Algorithm for Solving Nonlinear Equations (RESEARCH NOTE)
This paper presents a practical and efficient method to solve large-scale nonlinear equations. The global convergence of this new trust region algorithm is verified. The algorithm is then used to solve the nonlinear equations arising in an Expanded Lagrangian Function (ELF). Numerical results for the implementation of some large-scale problems indicate that the algorithm is efficient for these ...
