In this paper, we introduce a dynamic allocation investment mechanism into the spatial public goods game. In the model, if a cooperator i collects more payoffs from one group centered on the player j in the last round, he will put more investments to the group in the next round. The intensity of...

In this paper, we bring an unequal payoff allocation mechanism into evolutionary public goods game on scale-free networks and focus on the cooperative behavior of the system. The unequal mechanism can be tuned by one parameter α: if α0, the hub nodes can use its degree advantage to collect...
