A new version of extragradient method for variational inequality problems

, 2008
-In this paper, we propose a new version of extragradient method for the variational inequality problem. The method uses a new searching direction which differs from any one in existing projection-type methods, and is of a better stepsize rule.

Modified Noor's Extragradient Method for Solving Generalized Variational Inequalities in Banach Spaces

, 2020
Motivated and inspired by Korpelevich's and Noor's extragradient methods, we suggest an extragradient method by using the sunny nonexpansive retraction which has strong convergence for solving the generalized variational inequalities in Banach ...

Method for Approximating Solutions to Equilibrium Problems and Fixed-Point Problems without Some Condition Using Extragradient Algorithm

Axioms
The objective of this research is to present a novel approach to enhance the extragradient algorithm’s efficiency for finding an element within a set of fixed points of nonexpansive mapping and the set of solutions for equilibrium problems. Specifically,

Revisiting Stochastic Extragradient

, 2019
We consider a new extension of the extragradient method that is motivated by approximating implicit updates. Since in a recent work~\cite{chavdarova2019reducing} it was shown that the existing stochastic extragradient algorithm (called mirror-prox) of ...

Extragradient methods with complexity guarantees for hierarchical variational inequalities

CoRR
In the framework of a real Hilbert space we consider the problem of approaching solutions to a class of hierarchical variational inequality problems, subsuming several other problem classes including certain mathematical programs under equilibrium constraints, constrained min-max problems, hierarchical game problems, optimal control under VI ...

The modified extragradient method for nonexpansive multivalued mappings and variational inequality problems

, 2019
[[abstract]]In this paper, we prove the strong convergence of an approximating common element of the set of fixed points of a nonexpansive multivalued mapping and the set of solutions of a variational inequality problem for a monotone, Lipschitz ...
