  We show that evolution in a population of adaptive agents, repeatedly
competing for a limited resource, can come to an abrupt halt. This transition
from evolutionary to non-evolutionary behavior arises as the global resource
level is changed, and is reminiscent of a phase transition to a frozen state.
Its origin lies in the inductive decision-making of the agents, the limited
global information that they possess and the dynamical feedback inherent in the
system.
