摘要
引入了求解广义混合变分不等式的近似点-投影算法,证明了由算法所生成迭代序列强收敛于非扩张映射不动点集合与广义混合变分不等式解集合的公共元素.方法和结果是新的,且推广了这一领域内许多已知结果.
In this paper, we introduce the proximal-projection methods for finding the common element of the set of fixed points of nonexpansive mappings and the set of solutions of generalized mixed variational inequalities. Moreover,we also discuss the convergence criteria. Our approach and results are new and generalize many known resuhs in this field.
