A Primal-Dual Homotopy Algorithm for $ℓ_{1}$ -Minimization with $ℓ_{\infty}$ -Constraints

Christoph Brauer, Dirk A. Lorenz, Andreas M. Tillmann

In this paper we propose a primal-dual homotopy method for $ℓ_{1}$ -minimization problems with infinity norm constraints in the context of sparse reconstruction. The natural homoto…

Rank-optimal weighting or "How to be best in the OECD Better Life Index?"

Jan Lorenz, Christoph Brauer, Dirk A. Lorenz

We present a method of rank-optimal weighting which can be used to explore the best possible position of a subject in a ranking based on a composite indicator by means of a mathema…
