A TRUST REGION ALGORITHM FOR A CLASS OF COMPOSITE NONSMOOTH OPTIMIZATION
【摘要】 本文提出了一个易实施的处理一类无约束复合非光滑优化的信赖域算法,并在一定条件下证明了该算法所产生的迭代序列的任何聚点都是原问题的稳定点.
【Abstract】 In this paper, a trust region algorithm for a class of unconstrained problems in composite nonsmooth optimization is given. Under some conditions, we prove that each accumulation of the algorithm is a stationary point of the primitive problem.
