The projection methods proposed by Goldstein, Levitin and Polyak are the simplest iterative methods for solving monotone variational inequality problems.However, it is difficult to estimate the value of Lipschitz constant L and the strongly monotone modules α, which is necessary for the determination of the step-size in the method. In this paper, we propose an implementable step-size rule, which doesn't need the estimates of the value of L and α, and is almost as simple as the original one. Finally, we also present some numerical examples by using the proposed step size rule.
