Abstract
Summary
Regularized variants of conjugate gradient and componentwise gradient methods for solving the three-dimensional nonlinear inverse gravity problem of finding the density interface were constructed. The algorithms were parallelized and implemented for multicore processors and GPUs. The model problem with noised synthetic data was solved. The comparison of the proposed methods and the local corrections method in terms of iteration number, execution time and error of the solution was carried out.
