We obtain a strong convergence theorem for the sequences generated by these processes in Hilbert spaces. Based on this result we also get some new and interesting results. The results in this paper extend and improve some well-known results in the literature. Copyright 2009 Jian-Wen Peng et al.

Introduction Let H be a real Hilbert space with inner product and induced norm II II and let C be a nonempty-closed convex subset of H. Let p H R u X be a function and let F be a bifunction from C X C to R such that C n dom p 0 where R is the set of real numbers and dom p x e H y x X . Flores-Bazan 1 introduced the following generalized equilibrium problem Find x e C such that F x ỳ y y y x Ny 6 C. The set of solutions of is .
