Multi-Trajectory Parallel-in-Iteration Optimization
Guilherme H. M. Araujo, Oliver A. Krzysik, Hans De Sterck
Previously, we developed a ``parallel-in-iteration'' optimization framework that uses multigrid reduction-in-time (MGRIT) to parallelize slowly converging optimization methods, suc…
Parallel-in-iteration optimization using multigrid reduction-in-time
G. H. M. Araújo, O. A. Krzysik, H. De Sterck
Standard gradient-based iteration algorithms for optimization, such as gradient descent and its various proximal-based extensions to nonsmooth problems, are known to converge slowl…
Circumcentering approximate reflections for solving the convex feasibility problem
Guilherme Araújo, Reza Arefidamghani, Roger Behling +3
The circumcentered-reflection method (CRM) has been applied for solving convex feasibility problems. CRM iterates by computing a circumcenter upon a composition of reflections with…
