Large-scale optimization with the primal-dual column generation method
Jacek Gondzio, Pablo González-Brevis, Pedro Munari
The primal-dual column generation method (PDCGM) is a general-purpose column generation technique that relies on the primal-dual interior point method to solve the restricted maste…
A Second-Order Method for Strongly Convex L1-Regularization Problems
Kimon Fountoulakis, Jacek Gondzio
In this paper a robust second-order method is developed for the solution of strongly convex l1-regularized problems. The main aim is to make the proposed method as inexpensive as p…
Inexact Coordinate Descent: Complexity and Preconditioning
Rachael Tappenden, Peter Richtárik, Jacek Gondzio
In this paper we consider the problem of minimizing a convex function using a randomized block coordinate descent method. One of the key steps at each iteration of the algorithm is…
