改进的超梯度算法在无穷维Hilbert空间强收敛
Strong Convergence of Modified Extragradient Method in Infinite Hilbert Space
摘要
Abstract
Many methods have been proposed to solve Ⅵ(F,X). The simplest is the extragradient method which was proposed by G. M. Korpelevich( Matecon, 1976,12:747 -756. ). This method was modified by many scholars. Among all the algorithms, the method of paper (Y. J. Wang, N. H. Xiu, J. Z. Zhang. J Optim Theory Appl,2003,119:167 - 168. ) can use the convergence property of the generated sequences to verify the existence of solution without assuming the existence of the solution. This paper extends the midified extragradient method which was proposed by Y. J. Wang, N. H. Xiu and J. Z. Zhang to infinite-dimensional Hilbert space and discusses convergence properties of modified extragradient algorithm for pseudomonotone variational inequality in an infinite-dimensional Hilbert space.关键词
