Abstract—Through some modifications on the classic- Newton direction, we obtain a new searching direction for monotone horizontal linear complementarity problem. By taking the step size along this direction as one, we set up a full-step primal-dual interior point algorithm. The complexity bound for the algorithm is derived, and the result is the best-known for linear complementarity problem.
Index Terms—horizontal linear complementarity problem, interior-point algorithm, full-Newton step, complexity bound.
