A hybrid extragradient-viscosity method for monotone operators and fixed point problems
This paper deals with an iterative method, in a real Hilbert space, for approximating a common element of the set of fixed points of a demicontractive operator (possibly quasi-nonexpansive or strictly pseudocontractive) and the set of solutions of a variational inequality problem for a monotone, Lipschitz continuous mapping. The considered algorithm can be regarded as a combination of a variation of the hybrid steepest descent method and the so-called extragradient method. Under classical conditions, we prove the strong convergence of the sequences of iterates given by the considered scheme.
