Nous considérons dans cette thèse la complexité algorithmique de problèmes émanant de deux formalismes de raisonnement non-monotone: l'abduction et l'argumentation. Le premier est destiné à formaliser le processus de trouver des explications pour une manifestation observée, le second (et plus récent) offre un cadre théorique pour formaliser le processus de l'argumentation. Nous nous concentrons sur le problème d'existence d'une explication pour l'abduction et sur le problème d'existence d'un argument pour l'argumentation. Dans le cadre de la logique propositionnelle dans son ensemble ces problèmes sont considérés comme étant des tâches algorithmiques difficiles (ils sont souvent situés au deuxième niveau de l'hiérarchie polynomial). Notre b...
