摘要 给出了无约束非光滑优化问题的一种改进的信赖域算法。改进后的算法不仅满足全局收敛性,而且算法中增加的内循环在有限步内必终止,进一步减少了矩阵的运算量。最后给出一些初步的数值实验。 An improved trust region method of unconstrained non - smooth optimization problems is presented. The method meets the needs of global convergence ;the additional internal recycle of the method will surely be stopped in limited steps so that the matrix operation is reduced. At the end, some preliminary numerical experiments are given.
