Abstract:A modified inertial projection algorithm is proposed to find the common element of the set of pseudomonotone variational inequality problems and the fixed point set with a demicontractive mapping, and it is proved that the iterative sequence generated by the algorithm is strongly converged on a common element under the condition that the algorithm is implemented with a self-adaptive step size rule and the Lipschitz continuity. Finally, we implement some computational tests to show the efficiency and advantages of the proposed method.
Keywords:pseudomonotone variational inequality  fixed point  inertial projection and contraction method  demicontractive mapping  strong convergence
