| Abstract: | The derivative-free line search in literature[1] has not been well defined.We thus have proposed a new derivative-free line search.Based on this line search,we shew some useful properties of the approximately norm descent quasi-Newton algorithm and reached some conclusions.We then proved the global convergence. |

| Keywords: | nonlinear equations derivative-free line search global convergence |
