求解非线性方程组的L-M方法(英文)
ON L-M METHOD FOR NONLINEAR EQUATIONS
【摘要】 本文研究了求解奇异非线性方程组的Levenberg-Marquardt方法的收敛性.利用选取新的迭代参数求解非线性方程组的L-M方法,获得点列的超线性收敛性和二阶收敛性,并把试验结果与文献[19 ,20]的结果进行了比较.
【Abstract】 In this paper,we consider the convergence L-M method for solving a system of singular nonlinear equations.Through selecting a new parameter and giving a new L-M method,we show the local superlinear and quadratical convergence of the sequence generated by the new L-M method.Numerical experiments show that the method performs better for singular problems.
