Résumé. 2014 On présente une théorie de champ moyen pour les problèmes d’optimisation du type « Voyageur de Commerce » ou problèmes d’ « Appariement ». Cette théorie de champ moyen s’exprime à l’aide d’un ensemble infini de paramètres d’ordre, qui mesurent l’absence d’auto-moyen-nage du système et donc son degré de gel. On conjecture que la NP-complexité est associée à la brisure de symétrie des répliques. Abstract. 2014 A mean-field theory for optimization problems of the Travelling Salesman type, or of the Matching type, is presented. It involves an infinite set of order parameters which measure the lack of self-averageness of the system and its degree of freezing. We further conjecture that NP-completeness is associated with replica symm...
