AB  - In this study, a new search direction for Broyden family method is proposed for solving
unconstrained optimization problems. The new search direction is develop by hybridization the two search
direction in line search method known as quasi-Newton and conjugate gradient method under certain parameter.
This method is popular as Broyden-CG method. The suggestion method has an attractive properties which is
its search direction is sufficiently descent direction at every iteration. Under mild conditions, the researchers
prove that the proposed method has global convergence.
