针对非线性互补问题,构造一个新的光滑逼近函数,分析该函数的一些基本性质,再利用该函数建立求解非线性互补问题的光滑牛顿算法,证明在适当的条件下这一算法是全局及局部超线性收敛的,最后用数值算例验证该算法是有效的.
A new smoothing approximation function of NCP is given and some properties of function are analyzed.By this new function,a new Jacobian smoothing method for P0-NCP is proposed.The presented method is globally and locally superlinearly convergent under suitable conditions.Some numerical results show that this method is effective.
