The evolution of cooperation in the unidirectional division of labor on a tree network

The paper studies the evolution of cooperation in a unidirectional division of labor on a tree network using evolutionary game theory, finding that cooperation depends on costs rather than benefits and that sanction systems promote coexistence of cooperators and defectors.

The evolution of cooperation in the unidirectional linear division of labour of finite roles

The paper studies cooperation in a unidirectional division of labour with finite roles, finding that cooperation evolves based on the cost of cooperation and the probability of detecting defectors.
