Abstract: | A one-step smoothing Newton method is proposed for solving the vertical linear complementarity problem based on the so-called
aggregation function. The proposed algorithm has the following good features: (i) It solves only one linear system of equations and does only one line search at each iteration; (ii) It is well-defined for the vertical linear complementarity problem with vertical block P
0
matrix and any accumulation point of iteration sequence is its solution. Moreover, the iteration sequence is bounded for
the vertical linear complementarity problem with vertical block P
0
+R
0
matrix; (iii) It has both global linear and local quadratic convergence without strict complementarity. Many existing smoothing Newton
methods do not have the property (iii).
