| Abstract: | For the Quasi-Newton method of unconstrained optimizaton,J.A.Ford introduced a new algorithm which is obtained by constructing a nonlinear model with simple parameter for the objective function.In this paper,for the gradient we give a second order model with simple parameter.The structure of our model is simple and the parameter can be easily calculated. |
