A full-modified-Newton step infeasible interior-point method for monotone linear complementarity problem

By using a new search direction, we propose an infeasible interior-point method for monotone linear complementarity problem. The algorithm uses only one feasibility step in each iteration, and we prove that it suffices in order to obtain a polynomial-time method. The iteration bound coincides with the currently best iteration bound for linear complementarity problems. Moreover, the numerical results show that the new algorithm has a good performance.
