Exploring a strategy that leads to mutual cooperation without non-cooperative actions

September 24, 2019

Cooperation in mutual competition is a basic mechanism for the prosperity of human society. However, the simplest model of cooperation in game theory predicts that cooperation will not emerge among rational people because cooperative behaviors incur costs to cooperators, and free riding is a better option.

The team analyzed what strategy can promote and maintain a cooperative society in a basic model of a social dilemma called "the prisoner's dilemma" by introducing a new action of not participating in games. While previous studies could only analyze simple combinations of strategies, the research team used agent simulations and developed a method for visualizing more complex simulation results, enabling the research team to analyze adaptive strategies in an environment where approximately 20,000 strategies coexist and compete with each other.

They determined a strategy that can lead to mutual cooperation without using non-cooperative actions even when facing an exploiter. The strategy can be described as "escape interaction if a partner defected or cooperate if a partner escaped interaction".

Yamamoto says that cooperative society can be maintained without using the action of revenge if the action of escape is possible, and this may expand the research on the evolution of cooperation.
