非线性不等式组的牛顿法
Newton algorithm for nonlinear inequalities
【摘要】 采用引进具有二阶连续可微的辅助函数,将非线性不等式组转化为非线性方程组,然后利用牛顿迭代法对非线性方程组进行求解.算法具有局部快速收敛的性质,在一定条件下局部二阶收敛性也得到证明.数值试验表明算法是可行的.
【Abstract】 In is established the equivalence between the nonlinear inequalities with nonlinear equations by using auxiliary function,a descended Newton algorithm is proposed.It is proved the superlinear convergence of the algorithm in this paper,and under some conditions,it is local quadratic rate of convergence.Numerical examples are given to illustrate the method.
