| Abstract: | The difference coefficient was used to replace the exact derivative which is difficult to be computed, and a new algorithm was presented by using the idea of reduced gradient method. The reduced difference coefficient algorithm was shown to possess global convergence if the objective function is uniformly convex. |

| Keywords: | constrained optimization reduced difference coefficient difference coefficient global convergence uniformly convex |
