| Abstract | ||
| In this paper, we derive a new conjugate gradient method based expression of the denominator . In derivation of most CG- method it is assumed that the objective function is quadratic, therefore we begin with strictly convex quadratic function, we have proposed a new CG- method based on the quadratic model, and show that our method always produces a descent search direction and converges globally if the Wolfe conditions are satisfied. Numerical results indicate the efficiency of this method to solve the given test problems | ||
