The Research of Cooperative Emergence Mechanism of Donation Behaviors on Correlation Network

Cooperative behaviors as well as other altruistic behaviors exist everywhere in the realistic society. The prisoner´s dilemma demonstrates the conflict between individual interest and group interest. It has drawn great attention as a research prototype of reciprocal altruism. Complex networks provide a systematic framework for describing the game relationship between individuals. In this regard, this paper mainly studies prisoner´s dilemma game on correlation network and the influence of donation behaviors on cooperation. Donation behaviors which simulates individual´s pursuit of equalitarianism reflects the help the strong given to the weak and the reward to the co operators. We found that the cooperation and correlation probability have positive correlation. Donation behaviors between two correlation networks will not only promote cooperation on the corresponding network but also enhance its cooperation.
