摘要： 本文利用似距离泛函和似投影算子, 在有限维空间中建立了一类广义混合变分不等式的近似-似投影算法,证明了迭代序列是良定的, 在集值映像T为伪单调且上半连续、f是下半连续真凸的条件下证明了迭代序列收敛于广义混合变分不等式的解。

关键词: 广义混合变分不等式, 似投影算法, 似距离泛函, 伪单调映像

Abstract: In this paper,with the adoption of the proximate functional and proximate projection method proposed by Auslender and the establishment of the proximal projection-like method for solving generalized mixed variational inequalities in finite dimension spaces, two results are obtained. Firstly, the iterative sequence is well-defined. Then, every accumulation point of the sequence is a solution of generalized mixed variational inequalities under the condition that the set-valued mapping is pseudo-monotone mapping with upper semi-continuity and f is the lower semi-continuity true convex.

Key words: generalized mixed variational inequalities, projected-like method, proximate functional, pseudomonotone
