    Trust Region Newton With Dogleg Method
    (Addis Ababa University, 2018-05-02) Yeshitla, Abaye; Guta, Berhanu (PhD)
    In this project, we propose a trust region dogleg method algorithms to solve a trust region subproblems arising form unconstrained optimization. The method can deal with by constricting a dogleg paths. The case when the Hessian B of quadratic models is positive de nite. The philosophy and fundamental ideas of trust region algorithms are discussed and proved that the method is globally convergent and has a supper linear convergence rate. And then the nal algorithm is programmed in MATLAB and implemented by taking appropriate test problem.
