    Short Abstract (long version): This thesis addresses the problem of designing mechanisms that lead to socially desirable outcomes in dynamic double auction markets such as stock exchanges and group buying. The main challenge of the design is dealing with the uncertainty posed by the participants who are dynamically arriving and departing and their valuations vary over time. The thesis demonstrates the difficulties in designing mechanisms with desirable properties such as truthfulness, efficiency and budget balance. It also provides dedicated mechanisms satisfying those properties by using augmentation, reduction and behaviour-based approaches.

    (In French) Ce thèse a pour objet de concevoir des mécanismes d'allocation dans le contexte des enchères doubles dynamiques (achat groupés, bourses électroniques). Le principal défi inhérent à la conception de tels mécanismes est d'aboutir à un résultat socialement optimal alors que la dynamique induit une incertitude sur les arrivées et départs des participants de l'enchère ainsi que sur les valuations qui peuvent être fluctuantes. Dans cette thèse, nous proposons des mécanismes qui sont efficaces, incitatif et garantissant l'équilibre du budget. La définition de ces mécanismes s'appuient sur les algorithmes d'appareillage pour des graphes bipartis (technique d'augmentation et réduction) ainsi que sur une méthode générale prenant en compte le comportement des participants.

    Thesis: Decomposition of Multi-Player Games in General Game Playing (see a short/published verison): A General Game Playing system is one that can accept a formal description of a game and use such description to play the game effectively without human intervention. Unlike specialized game players, such as Deep Blue, general game players are able to play arbitrary games, which cannot rely on algorithms designed in advance for specific games. Decomposition search solves very large game (in terms of game tree) in exponentially smaller subgames, i.e. it will be exponentially faster.
