Abstract. The variational inequality problem is reduced to an optimization
problem with a differentiable objective function and simple bounds. Theo
retical results are proved, that relate stationary points of the minimization
problem to solutions of the variational inequality problem. Perturbations
of the original problem are studied and an algorithm that uses the smooth
minimization approach for solving monotone problems is defined.
