摘    要:在非线性互补问题解存在的情况下,给出求解此类问题的一类新的算法。首先将非线性互补问题转化为多目标优化,给出多目标优化问题零有效解的定义;进而得到多目标优化问题的零有效解,即非线性互补问题的最优解,最后采用极大极小方法求解转化后的多目标优化问题。数值模拟结果表明该方法的正确性和有效性.

Abstract: A new method was proposed for the nonlinear complementarity problem (NCP) under the condition that the solution exists. The NCP was formulated into a multiobjective optimization problem (MOP), and a zero-efficient solution of the MOP was defined. Then the zero-efficient solution of the MOP was also indicated to be the solution of the NCP. Finally the minimax method was used for the MOP. Numerical results indicate that the proposed method is effective.
