| Abstract: | In this paper,a kind of new Armijo type line search conditions is presented on the basis of several common types of Armijo line search,which guarantees the global convergence of the hybrid conjugate gradient method proposed by Du etc.Numerical experiments show that the new method is effective for the given test functions. |

| Keywords: | unconstrained optimization conjugate gradient method Armijo line search global convergence |
