Modified modulus-based matrix splitting algorithms for a class of weakly nondifferentiable nonlinear complementarity problems

By reformulating a class of weakly nonlinear complementarity problems as implicit fixed-point equations based on splitting of the system matrix, a modified modulus-based matrix splitting algorithm is presented. The convergence analysis of proposed algorithm is established for the case that the splitting of the system matrix is an H-splitting. Numerical experiments on two model problems are given to illustrate the theoretical results and examine the numerical effectiveness.
