| Abstract: | In this paper, an improved algorithm on the simplex method for nonlinear least squares estimation is presented. This improved simplex method combined the advances of fast convergence and great probability for global optimization. Two examples are set to justify that the method is excellent simplex method in global optimization, and it＇ s suitable for nonlinear funtion optimization in survey technology. |
