We investigate the dynamics of the choice of an active strategy in the
minority game. A history distribution is introduced as an analytical tool to
study the asymmetry between the two choices offered to the agents. Its
properties are studied numerically. It allows us to show that the departure
from uniformity in the initial attribution of strategies to the agents is
important even in the efficient market. Also, an approximate expression for the
variance of the number of agents at one side in the efficient phase is
proposed. All the analytical propositions are supported by numerical
simulations of the system.Comment: Latex file, 17 page, 4 figure
