Abstract: In this paper, we study the solution of the variational inequality KKT systems. A new NCP function is used to convert KKT conditions of variational inequalities into an equivalent smooth equation. And a smoothing Newton method for solving the nonlinear complementarity problem of NCP function is established, and the convergence and local convergence of the algorithm are obtained, and the accuracy of the theoretical analysis is verified by numerical experiments.
