在将非线性互补问题转化为求解非光滑方程组的基础上,为了将非线性互补问题转化为求解光滑方程组,通过引入一个新的光滑NCP函数,建立了求解P0函数非线性互补问题的一步光滑牛顿法,并在较弱的条件下证明了该算法具有良好的适定性和全局收敛性。
The nonlinear complementarity problem (denoted by NCP (F)) can be reformulated as the solution of a nonsmooth system of equations. By introducing a new smoothing NCP-function, the problem is approximated by a family of parameterized smooth equations, A one-step smoothing Newton method is proposed for solving the nonlinear complementarity problem with P0-function (P0-NCP) based on the new smoothing NCP-function. The proposed algorithm has been proved to be well-defined and globally convergent under weaker conditions.
