Introducing the method of ellipcenters, a new first order technique for unconstrained optimization
Roger Behling, Ramyro Aquines Correa, Eduarda Ferreira Zanatta +1
In this paper, we introduce the Method of Ellipcenters (ME) for unconstrained minimization. At the cost of two gradients per iteration and a line search, we compute the next iterat…
Basis pursuit by inconsistent alternating projections
Roger Behling, Yunier Bello-Cruz, Luiz-Rafael Santos +1
Basis pursuit is the problem of finding a vector with smallest -norm among the solutions of a given linear system of equations. It is a well-known convex relaxation of the…
Parallel Polyhedral Projection Method for the Convex Feasibility Problem
Pablo Barros, Roger Behling, Vincent Guigues
In this paper, we introduce and study the Parallel Polyhedral Projection Method (3PM) and the Approximate Parallel Polyhedral Projection Method (A3PM) for finding a point in the in…
On circumcentered direct methods for monotone variational inequality problems
Roger Behling, Yunier Bello-Cruz, Alfredo Iusem +2
Circumcentered techniques have been shown to significantly accelerate projection-based methods for convex feasibility problems. Motivated by this success, we propose two direct met…
Parallelizing the Circumcentered-Reflection Method
Pablo Barros, Roger Behling, Vincent Guigues +1
This paper introduces the Parallelized Circumcentered Reflection Method (P-CRM), a circumcentric approach that parallelizes the Circumcentered Reflection Method (CRM) for solving C…
