摘要 将多层迭代法应用于不适定算子方程的数值求解,给出了利用离散偏差原则确定正则化参数进而求出近似解的快速算法。文章对算法误差进行了理论分析,并通过算例说明方法的有效性。 The multilevel iteration method is applied to solve ill-posed operator equations of the first kind. Based on the discrete discrepancy principle, the fast algorithm for approximate solution and regularization parameter is given. The error estimate is obtained and the numerical experiment for integral equation of the first kind is presented to illustrate the efficiency of the algorithm.
