Difference in Choice Based on Type and Time

Caption

In the first group (Well-mixed) where the opponents were reshuffled each round, defectors prevailed over the course of 50 rounds. In the second group (Network reciprocity) where the opponents remained the same for the 50 rounds enabling them to identify cooperative neighbors, the cooperative cluster survived. In the third group (Network reciprocity with punishment), the option to punish opponents failed to boost cooperation.
