Résumé

Nous considérons l'approximation de programmes mathématiques à deux niveaux par des problèmes résolubles du même type, c'est-à-dire des problèmes bi-niveaux avec une approximation linéaire de l'objectif de premier niveau et de toutes les contraintes et une approximation quadratique de la fonction objectif de second niveau. Nous décrivons les principales caractéristiques de l'algorithme et le logiciel qui l'accompagne. Les résultats numériques préliminaires semblent confirmer le caractère remarquable de la méthode.
