| 摘 要： | 对无约束最优化问题给出了一类具有降维和记忆功能的子空间信赖域算法。该方法既有信赖域算法的特点，又有多信息下降法的特点，故收敛速度较快，初步的数值试验也证实了这一点。

| Abstract: | A New restricted trust region method for unconstrained optimization is presented, in which the trust region is a box. Since the method possesses the characteristics of both the trust region method and the supermemory descent method, it is endowed with rapidly convergence. Numerical tests illustrate this point. |
