求解非线性最小二乘问题的迭代法

Iterative Method for Solving Nonlinear Least-Squares Problems

基于解线性方程组的Jacobi迭代法的思想 ,本文提出了一种求解非线性最小二乘问题的迭代法 ,大量的数值试验表明该迭代法具有较好的收敛性 另外 。

We present an iterative method for solving nonlinear least squares problems,on the basis of Jacobi method for solving system of linear equations,where numerical experiments show quite promising performance of the parallel algorithm. Furthermore,we parallelize the proposed iterative method so that it is more efficiently large scale problems.
