Parallel multigrid method for solving inverse problems

open access: yesMethodsX, 2022
We considered in this work the linear operator equation and used the Landweber iterative method as an iterative solver. After that, we used the multigrid method as an optimization method for obtaining an approximation solution with a highly accurate and ...
