Fast Krasnoselskii-Mann Method with Overrelaxation and Preconditioners
Radu I. Boţ, Enis Chenchene, Jalal M. Fadili
We study accelerated Krasnoselskii-Mann-type methods with preconditioners in both continuous and discrete time. From a continuous-time model, we derive a generalized fast Krasnosel…
Extra-Gradient Method with Flexible Anchoring: Strong Convergence and Fast Residual Decay
Radu Ioan Boţ, Enis Chenchene
In this paper, we introduce a novel Extra-Gradient method with anchor term governed by general parameters. Our method is derived from an explicit discretization of a Tikhonov-regul…
Constrained Consensus-Based Optimization and Numerical Heuristics for the Few Particle Regime
Jonas Beddrich, Enis Chenchene, Massimo Fornasier +2
Consensus-based optimization (CBO) is a versatile multi-particle optimization method for performing nonconvex and nonsmooth global optimizations in high dimensions. Proofs of globa…
