Abstract
The aim of this paper is to introduce and study a new iterative algorithm for finding a common element of the set of fixed points of a finite family of multivalued strictly pseudo-contractive mappings and the set of solutions of equilibrium problems in Hilbert spaces. Strong convergence of the proposed method is established under suitable control conditions. Application to optimization problems with constraints is provided to support our main results. Furthermore, numerical example is given to demonstrate the implementability of our algorithm.The algorithm and its convergence results improve and develop previous results in the field.
