The European Physical Journal B 13, R419 (2000) The minority model was introduced to study the competition between agents
with limited information. It has the remarkable feature that, as the amount of
information available increases, the collective gain made by the agents is
reduced. This crowd effect arises from the fact that only a minority can profit
at each moment, while all agents make their choices using the same input. We
show that the properties of the model change drastically if the agents make
choices based on their individual stories, keeping all remaining rules
unaltered. This variation reduces the intrinsic frustration of the model, and
improves the tendency towards cooperation and self organization. We finally
study the stable mixing of individual and collective behavior.
