Variable Stepsize Distributed Forward-Backward Splitting Methods as Relocated Fixed-Point Iterations
Felipe Atenas, Minh N. Dao, Matthew K. Tam
We present a family of distributed forward-backward methods with variable stepsizes to find a solution of structured monotone inclusion problems. The framework is constructed by me…
Linear convergence of relocated fixed-point iterations
Felipe Atenas, Farhana Ahmed Simi, Matthew K Tam
We establish linear convergence of relocated fixed-point iterations as introduced by Atenas et al. (2026) DOI: 10.1137/25M1776810 assuming the algorithmic operator satisfies a line…
Relocated Fixed-Point Iterations with Applications to Variable Stepsize Resolvent Splitting
Felipe Atenas, Heinz H. Bauschke, Minh N. Dao +1
In this work, we develop a convergence framework for iterative algorithms whose updates can be described by a one-parameter family of nonexpansive operators. Within the framework,…
A distributed proximal splitting method with linesearch for locally Lipschitz gradients
Felipe Atenas, Minh N. Dao, Matthew K. Tam
In this paper, we propose a distributed first-order algorithm with backtracking linesearch for solving multi-agent minimisation problems, where each agent handles a local objective…
