类惯性法解零点问题的收敛性及其应用

On the convergence and applications of the inertial-like method for null-point problems

Yan Tang, Shiqing Zhang

摘要:

本文提出了两种新的求解集值极大算子分裂公共零点问题(SCNPP)的类惯性算法。该算法的特点是采用了新的惯性结构(即新的类惯性方法的设计既不需要预先计算$x_n$与$x_{n-1}$之差的范数,也不需要考虑惯性参数$θ_n$的特殊值来使条件$\sum_{n=1}^\infty α_n\|x_n-x_{n-1}\|^2<\infty$成立),而且步长的选择不需要先验的算子范数知识。数值实验来说明算法的性能。

英文摘要:

In this paper, we propose two novel inertial-like algorithms for solving the split common null point problem (SCNPP) with respect to set-valued maximal operators. The features of the presented algorithm are using new inertial structure (i.e, the design of the new inertial-like method does neither involve computation of the norm of the difference between $x_n$ and $x_{n-1}$ in advance, nor need to consider the special value of the inertial parameter $θ_n$ to make the condition $\sum_{n=1}^\infty α_n\|x_n-x_{n-1}\|^2<\infty$ valid) and the selection of the step-sizes does not need prior knowledge of operator norms. Numerical experiments are presented to illustrate the performance of the algorithms.
