| Abstract: | This paper proposes a modified Liu-Storey（LS） conjugate gradient Algorithm.The method can guarantee that the search direction is a sufficient descent direction at each iteration.It is proved that the method is strongly globally convergent under two different Armijo-type line searches. |
