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…

Accelerating Diagonal Methods for Bilevel Optimization: Unified Convergence via Continuous-Time Dynamics

Radu Ioan Boţ, Enis Chenchene, Ernö Robert Csetnek +1

We analyze fast diagonal methods for simple bilevel programs. Guided by the analysis of the corresponding continuous-time dynamics, we provide a unified convergence analysis under…

On the equivalence of a Hessian-free inequality and Lipschitz continuous Hessian

Radu I. Boţ, Minh N. Dao, Tianxiang Liu +2

It is known that if a twice differentiable function has a Lipschitz continuous Hessian, then its gradients satisfy a Jensen-type inequality. In particular, this inequality is Hessi…

A full splitting algorithm for fractional programs with structured numerators and denominators

Radu Ioan Boţ, Guoyin Li, Min Tao

In this paper, we consider a class of nonconvex and nonsmooth fractional programming problems, that involve the sum of a convex, possibly nonsmooth function composed with a linear…
