Noise-induced enhancement of network reciprocity in social dilemmas.

Highlights: [•] We introduce the noise-induced mechanism into the prisoner’s dilemma game. [•] Cooperation will be largely enhanced by introducing the noise into the calculation of fitness. [•] Despite the defectors prevail initially, the stressed factor still promotes the cooperation. [•] The mechanism studied here is helpful on different kinds of interaction networks.
