The $ω$ -Condition Number: Applications to Optimal Preconditioning and Low Rank Generalized Jacobian Updating

Woosuk L. Jung, David Torregrosa-Belén, Henry Wolkowicz

Preconditioning is essential in iterative methods for solving linear systems. It is also the implicit objective in updating approximations of Jacobians in optimization methods, e.g…

The Boosted Double-Proximal Subgradient Algorithm for Nonconvex Optimization

Francisco J. Aragón-Artacho, Pedro Pérez-Aros, David Torregrosa-Belén

In this paper we introduce the Boosted Double-proximal Subgradient Algorithm (BDSA), a novel splitting algorithm designed to address general structured nonsmooth and nonconvex math…
