    • Abstract:
      The article introduces a new simulation model for the study of cooperation in groups based on the repeated prisoner's dilemma game. The prisoner's dilemma game, which is used to interpret ethnographic data, likewise focuses attention on the dilemma posed by the contrast between the immediate benefits of exploitation and the long-term benefits of cooperation. Through the use of large-scale computational resources, the stimulation of the detailed microscopic behavior of identifiable individuals in the group who interact and make decisions according to a set of rules has been identified. Upon examining the macroscopic behavior of the group using the new simulation, it has been found out that cooperation can be sustained in large groups when there are sufficient interactions on each round.
