dc.description1st Regional Conference on Applied and Engineering Mathematics (RCAEM-I) 2010 organized by Universiti Malaysia Perlis (UniMAP) and co-organized by Universiti Sains Malaysia (USM) & Universiti Kebangsaan Malaysia (UKM), 2nd - 3rd June 2010 at Eastern & Oriental Hotel, Penang.en_US
dc.description.abstractIn this paper, we propose a new multi-step quasi- Newton method for solving unconstrained optimization problem. Our new gradient method is a in the frame of Barzilai and Borwein method. A multi step method is used to improve an accuracy of Hessian approximation which is in a diagonal matrix form. By incorporating a simple monotone strategy, the global convergence of our new method is achieved. Numerical results show the superiority of proposed method in compare with the BB method.en_US
