Abstract:

In this paper, by introducing the modulus-based nonlinear function and extending the classical Newton method, we investigate an accelerated Newton iteration method with high-order convergence for solving a class of weakly nonlinear complementarity problems which arise from the discretization of free boundary problems. Theoretically, the performance of high-order convergence is analyzed in details. Some numerical experiments illustrate the feasibility and efficiency of the proposed method.

Key words: Weakly nonlinear complementarity problems, High-order convergence, The modulus-based nonlinear function, Free boundary problems, Accelerated Newton method
