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