| Abstract: | In this paper,two classes of modified HS conjugate gradient methods is proposed to solve unconstrained optimization problems.And,under Wolfe line search conditions,this paper proves their global convergence without the given sufficient descent condition.Many numerical experiments show that they are very efficient and robust,and they can be widely used in scientific computation. |
