摘要：Based on a modified secant equation, a new parameter conjugate gradient method is proposed. Information of both gradient and function of objective function is considered in our method. The proposed method always produces a descent search direction and is shown to be globally convergent under reasonable assumptions. Numerical results are reported to show the efficiency of the proposed methods. ? 2015 by Binary Information Press
