Modified two-step extragradient method for solving the pseudomonotone equilibrium programming in a real Hibert space

Yordsorn, Pasakorn,  Kumam, Poom and  Rehman,  Habib-ur



The purpose of this paper is to come up with an inertial extragradient method for dealing with a class of pseudomonotone equilibrium problems. This method can be a view as an extension of the paper title “A new two-step proximal algorithm of solving the problem of equilibrium programming” by Lyashko and Semenov et al. (Optimization and Its Applications in Control and Data Sciences: 315–-325, 2016). The theorem of weak convergence for solutions of the pseudomonotone equilibrium problems is well-established under standard assumptions placed on cost bifunction in the structure of a real Hilbert spaces. For a numerical experiment, we take up a well-known Nash Cournot equilibrium model of electricity markets to support the well-established convergence results and be adequate to see that our proposed algorithms have a competitive superiority over the time of execution and the number of iterations.
