摘要
提出了一个新的求解非线性方程组的滤子算法,首先把非线性方程组的求解转化成一个非线性优化问题,然后借助非单调技术和滤子技术求解该问题,从而得到了原方程组的解.在适当的条件下,证明了该算法的全局收敛性,初步的数值试验表明了该算法的有效性.
This paper presents a new filter method for solving nonlinear equations. First, this problem is transformed into a nonlinear optimization. Then, it solves this question with the aid of nonmonotone technology and filter technology, and thus obtains a solution of the original nonlinear equation. Under reasonable conditions, it shows the global convergence properties. Preliminary numerical tests have proved the efficiency of the approach.
