Zowe次梯度算法的一个推广

An Extension of Zowe′s Subgradient Algorithm

将Ｚｏｗｅ提出的一个求解凸优化问题的次梯度法推广为基于ε－次梯度的算法，并且证明了当参数ε按某一原则变化时。

In this paper, Zowe′s subgradient algorithm for solving convex optimization problem is extended to a ε-subgradient based algorithm, which is proved to keep the global convergence if the parameter ε takes values according to some suitable criteria.
