摘要
考虑利用Tikhonov正则化方法求解线性不适定问题。基于吸收Morozov相容性原理,提出了一种新的选取正则化参数的迭代算法。该算法简单易实现且具有全局收敛性。给出了算法的收敛性分析,并通过数值算例说明了其数值有效性。
Considering solving the linear ill-posed problem by Tikhonov regularization,we propose a new iterative algorithm for choosing the regularization parameter based on the damped Morozov discrepancy principle.This algorithm is easy to implement and has global convergence.We give its convergence analysis,and show the numerical validity by numerical examples.
