摘要/Abstract

摘要：

2020 年, Liu 和 Yang 在 Hilbert 空间中提出了一种求解拟单调变分不等式的投影算法. 该文介绍了一种新的惯性系数来加速 Liu 和 Yang 文中的算法, 并在相同的假设条件下得到了算法的全局弱收敛性. 数值实验表明适当选取参数后的惯性方法比 Liu 和 Yang 文中的算法有更少的迭代步数和计算机耗时.

Abstract:

In 2020, Liu and Yang proposed a projection algorithm (LY for short) for solving quasimonotone variational inequality in Hilbert Space. In this paper, by taking a new inertia coefficient, we present an inertial technique to accelerate LY. Under the same assumptions, the global weak convergence of the sequence generated by this algorithm is obtained. Numerical experiments show that the new algorithm can accelerate LY from the point view of iterate number steps and the point view of CPU time cost by taking suitable parameters.

Key words: Variational inequality, Projection algorithm, Quasimonotone, Inertial method
