On the asymptotical regularization with convex constraints for inverse problems
Min Zhong, Wei Wang
In this paper, we consider the asymptotical regularization with convex constraints for nonlinear ill-posed problems. The method allows to use non-smooth penalty terms, including th…

A fast two-point gradient algorithm based on sequential subspace optimization method for nonlinear ill-posed problems
Guangyu Gao, Bo Han, Shanshan Tong
In this paper, we propose and analyze a fast two-point gradient algorithm for solving nonlinear ill-posed problems, which is based on the sequential subspace optimization method. A…
