摘要: 提出了一个求解非线性互补问题的熵函数社会认知优化算法。首先将非线性互补问题转化为非线性方程组来求解,然后利用熵函数法将非线性方程组求解转化为一个光滑的无约束优化问题,最后应用社会认知优化算法求解此优化问题。实验结果表明,该算法收敛速度快,稳定性好,是求解非线性互补问题的一种有效算法。

Abstract: Social Cognitive Optimization algorithm(SCO) based on entropy function for solving Nonlinear Complementarity Problem(NCP) is presented.Firstly NCP is transformed into nonlinear equations,and then an entropy function method is used to transform the solving nonlinear equations into a smooth function of unstrained optimization problems.Finally,SCO algorithm is introduced to solve the NCP.The imitate results manifest that SCO converges fast and stably,and it is an effective algorithm for NCP.

Key words: Cognitive Optimization algorithm(SCO), Nonlinear Complementarity Problem(NCP), entropy function
