| Abstract: | We propose a trust region interior algorithm for solving nonlinear equality systems subject to bound constraints on variables. Under some reasonable conditions, the proposed algorithm is globally convergent and has locally fast convergent rate. Results of numerical experiments are reported to show the effectiveness of the proposed algorithm. |

| Keywords: | trust region method interior points nonlinear equation |
