摘要

该文在Hilbert空间中提出具有惯性项的Tseng型外梯度算法,找到了拟单调变分不等式问题与半压缩映射的不动点问题的公共解.在拟单调和一致连续的条件下,获得了算法所生成序列的强收敛性.最后,通过一些数值例子说明了该算法的有效性.

Abstract

In this paper,we introduce a new inertial Tseng's extragradient algorithm for finding a common element of the set of solutions of a quasimonotone variational inequality problem and the set of fixed points of a demicontractive mapping in real Hilbert spaces.The strong convergence of the algorithm is proved under quasimonotone and uniformly continuous assumptions of the variational inequality mapping.Finally,some numerical examples illustrate the effectiveness of our algorithm.
