Approaches to iterative algorithms for solving nonlinear equations with an application in tomographic absorption spectroscopy
F. J. Aragón-Artacho, W. Cai, Y. Censor +3
In this paper we propose an approach for solving systems of nonlinear equations without computing function derivatives. Motivated by the application area of tomographic absorption…

A primal-dual splitting algorithm for composite monotone inclusions with minimal lifting
Francisco J. Aragón-Artacho, Radu I. Boţ, David Torregrosa-Belén
In this work, we study resolvent splitting algorithms for solving composite monotone inclusion problems. The objective of these general problems is finding a zero in the sum of max…

A direct proof of convergence of Davis-Yin splitting algorithm allowing larger stepsizes
Francisco J. Aragón-Artacho, David Torregrosa-Belén
This note is devoted to the splitting algorithm proposed by Davis and Yin in 2017 for computing a zero of the sum of three maximally monotone operators, with one of them being coco…
