| 摘 要： | 利用凝聚函数一致逼近非光滑极大值函数的性质,将非线性互补问题转化为参数化光滑方程组.然后,对此方程组给出了一种微分方程解法,并且证明了非线性互补问题的解是微分方程系统的渐进稳定平衡点.在适当的假设条件下,证明了所给出的算法具有二次收敛速度.数值结果表明了此算法的有效性.

| Abstract: | By using a smooth aggregate function to approximate the non-smooth max-type function,nonlinear complementarity problem can be treated as a family of parameterized smooth equations.Then,a differential equation approach is proposed to solve such a system.It is proven that the solution of the nonlinear complementarity problem is an asymptotically stable equilibrium point of the proposed differential system.Under mild hypothesis,the local quadratic rate of this algorthm is proved,and illustrative examples are given. |
