We introduce an iterative method for finding a common element of the set of solutions of an equilibrium problem and of the set of fixed points of a finite family of nonexpansive mappings in a Hilbert space. We prove the strong convergence of the proposed iterative algorithm to the unique solution of a variational inequality, which is the optimality condition for a minimization problem.
Let H be a Hilbert space and let C be a closed, convex and nonempty subset of H. If T : C → H is a non-self and non-expansive mapping, we can define a map h : C → R by h(x) := inf{λ ≥ 0 : λx + (1 -λ)Tx ∈ C}. Then, for a fixed x 0 ∈ C and for α 0 := max{1/2, h(x 0 )}, we define the Krasnoselskii-Mann algorithm x n+1 = α n x n + (1 -α n )Tx n , where α n+1 = max{α n , h(x n+1 )}. We will prove both weak and strong convergence results when C is a strictly convex set and T is an inward mapping.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
