An active-set method for sparse approximations. Part II: General piecewise-linear terms
Spyridon Pougkakiotis, Jacek Gondzio, Dionysios S. Kalogerias
In this paper we present an efficient active-set method for the solution of convex quadratic programming problems with general piecewise-linear terms in the objective, with applica…
An inexact potential reduction method for linear programming
Lukas Schork, Jacek Gondzio
A class of interior point methods using inexact directions is analysed. The linear system arising in interior point methods for linear programming is reformulated such that the sol…
A Preconditioner for a Primal-Dual Newton Conjugate Gradients Method for Compressed Sensing Problems
Ioannis Dassios, Kimon Fountoulakis, Jacek Gondzio
In this paper we are concerned with the solution of Compressed Sensing (CS) problems where the signals to be recovered are sparse in coherent and redundant dictionaries. We extend…
A Second-Order Method for Compressed Sensing Problems with Coherent and Redundant Dictionaries
Ioannis Dassios, Kimon Fountoulakis, Jacek Gondzio
In this paper we are interested in the solution of Compressed Sensing (CS) problems where the signals to be recovered are sparse in coherent and redundant dictionaries. CS problems…
