Iterative Newton type algorithms and its applications to inverse gravimetry problem

The paper gives a brief overview of approaches to the construction of iterative processes of the Newton and gradient type for stable approximation of solutions to nonlinear irregular operator equations in Hilbert spaces. For two-stage algorithms based on Lavrentiev regularization scheme and a modified Newton's method the convergence theorem are formulated and the results of numerical solution to three-dimensional inverse gravimerty problem for two-layer model are discussed.
