Solving box constrained variational inequalities by using the natural residual with D-gap function globalization

We present a new method for the solution of the box constrained variational inequality problem, BVIP for short. Basically, this method is a nonsmooth Newton method applied to a reformulation of BVIP as a system of nonsmooth equations involving the natural residual. The method is globalized by using the D-gap function. We show that the proposed algorithm is globally and fast locally convergent. Moreover, if the problem is described by an a ne function, the algorithm has a nite termination property. Numerical results for some large-scale variational inequality problems are reported.
