  We study a recently proposed model in which an odd number of agents are
competing to be in the minority. The agents have one strategy in hand which is
to follow the most recent history. Each agent is also assigned a value p, which
is the probability that an agent will follow the trend. Evolution is introduced
through the modification of the value of p when the performance of an agent
becomes unsatisfactory. We present numerical results for the distribution of p
values in the population as well as the average duration between modifications
at a given p for different values of the parameters in the model. We also point
out the difference between the present model and a slightly modified model in
which a strategy is randomly assigned to every agent initially.
