This paper mainly studies the cooperative evolution of game model on the regular lattice,
and to explore factors that influence the evolution of cooperation, including proportion of initial
betrayers, the game model, the profit ratio, the number of neighbors that profit information, and the
policy update rules. The results show that: Different factors have different effects on the evolution of
cooperation. The proportion of initial traitors has no effect on the evolution of cooperation (except in
extreme cases). The profit ratio has a great influence on the evolution of cooperation. The different
profit ratio has a direct impact on the stability of cooperation evolution, and the stable state of the
profit ratio between 1.8 and 2.0 is almost the same. Policy update rules are the most important factors
affecting the evolution of cooperation, and different rules determine the ratio of cooperation when the
evolution of cooperation is stable. With the increase in the number of neighbors that profit information,
the ratio of cooperation is steadily rising when cooperation is stable. Prisoner's dilemma is more
cooperative than snowdrift game.
