We describe a simple and robust procedure for freezing out chaotic
behavior in systems composed of interacting agents making decisions
based on imperfect and delayed information. It is based on a reward
mechanism whereby the relative number of computational agents following
effective strategies is increased at the expense of the others. This
procedure, which generates a diverse population out of an essentially
homogeneous one, is able to control chaos through a series of dynamical
bifurcations into a stable fixed point. Stability boundaries are
computed and the minimal amount of diversity required in the system is
established.
