Abstract:
In this paper, a new formula of main parameter dk of memroy gradient method is proposed,and is analyzed the global convergence and convergence rate of this method with Wolfe-Powell line search rule. Numerical results show that the new method is efficient, and it can be used in large scale optimization problems.[著者文摘]
Key words:
memory gradient method; Wolfe-Powell line search; convergence
