In this paper, we propose a new modify of DFP
update with a new extended quasi-Newton condition for unconstrained optimization problem so called
update. This update is based on a new Zhang Xu condition we show that
update preserves the value of determinant of the next Hessian matrix equal to the value of determinant of current Hessian matrix theoretically and practically. Global convergence of the modify is established. Local and super linearly convergence are obtained for the proposed method. Numerical results are given to compare a performance of the modify
method with the standard DFP
method on same function is selected.
