Le prochain séminaire de l’équipe Mokaplan aura lieu le **mercredi 23 janvier à 10h30** à l’INRIA Paris (2 rue Simone Iff) en salle **Jacques-Louis Lions 1.**

Nous aurons le plaisir d’écouter Pierre WEISS (CNRS/ ITAV) et Luca NENNA (Université Paris-Sud).

- Exposé de Pierre WEISS:

**Titre:** A convergence analysis of some exchange algorithms

**Résumé: **

Exchange algorithms are a class of optimization methods to solve semi-infinite programs: optimization problems over a finite dimensional variable with an infinite number of constraints. These problems arise naturally in a variety of situations. We will focus here on their use for the resolution of inverse problems without discretization of the underlying domain. A typical example is super-resolution by using a total variation regularizer. Our main result states the linear convergence rate of the method under technical assumptions such as a non degeneracy condition.
