凸函数极小化的非单调共轭次梯度型方法

A Non-Monotone Conjugate Subgradient Type Method for Minimization of Convex Functions

Igor Konnov

摘要:

本文提出了一个求解凸不可可微函数极小化问题的共轭次梯度型方法。与该类的自定义方法不同,它不需要目标函数的单调递减,从本质上降低了每次迭代的实现成本。同时,它的步长过程考虑了该方法沿迭代点的行为。计算实验的初步结果证实了所提出的修改的效率。

英文摘要:

We suggest a conjugate subgradient type method without any line-search for minimization of convex non differentiable functions. Unlike the custom methods of this class, it does not require monotone decrease of the goal function and reduces the implementation cost of each iteration essentially. At the same time, its step-size procedure takes into account behavior of the method along the iteration points. Preliminary results of computational experiments confirm efficiency of the proposed modification.
