Impact of individual difference and investment heterogeneity on the collective cooperation in the spatial public goods game

作者：

Highlights：

• A novel PGG model with individual difference and investment heterogeneity is proposed.

• The individual difference is implemented by classifying the individuals into two classes.

• The investment heterogeneity is carried out through dynamic adjustment of contributions of cooperators.

• The nontrivial evolution of cooperation will be presented in the spatial PGG.
