Boosting cooperation in games with historical payoffs leads to societal harmony
In a voluntary prisoner's dilemma game, adding historical payoff can boost cooperation. By adjusting a parameter called w, the impact of historical payoff on players' fitness is controlled. When w is increased, cooperation increases, especially for small benefits. For larger benefits, a balance of strategies emerges, preventing one from dominating. This shows that historical payoff can help cooperation evolve positively in the game.
