  We study a modified prisoner's dilemma game taking place on two-dimensional
disordered square lattices. The players are pure strategists and can either
cooperate or defect with their immediate neighbors. In the generations each
player update its strategy by following one of the neighboring strategies with
a probability dependent on the payoff difference. The neighbor selection obeys
a dynamic preferential rule, i.e., the more frequently a neighbor's strategy
was adopted by the focal player in the previous rounds, the larger probability
it will be chosen to refer to in the subsequent rounds. It is found that
cooperation is substantially promoted due to this simple selection mechanism.
Corresponding analysis is provided by the investigations of the distribution of
players' impact weights, persistence, and as well as correlation function.
