Le modèle à Temporalité: pour un équilibre entre adéquation et optimisation du temps dans les simulations agent

ABSTRACT . If in reality we can only undergo time, multi-agent simulations allow us to use it as an evolution engine on reduced models in order to deduce some new knowledge about the real world. In addition, the way in which virtual time is managed by simulator influences a lot its potential uses. In this paper we review different existing approaches of time management. Concessions made in trying to adapt time to the model are systematically sanctioned by the impossibility of optimizing the simulation in order to reduce its execution time. However this criterion becomes increasingly significant with the increasing complexity of simulated models. After having established the set of requirements which a scheduling mechanism must satisfy, we show that an approach exists which, while satisfying these requirements, combines the adequacy and the optimization of time in multi-agent simulations.
