Environmental variability promotes the evolution of cooperation among geographically dispersed groups on dynamic networks
Fig 1
Relationships, geographical structure, and EV.
Each small circle within the gray circle represents a group (agent, node), with the number inside indicating the resource value. The gray ring represents the geographical structure, and each line connecting agents denotes a relationship (edge). (a) In the RV model, the prime node shifts randomly within the geographical structure, and resources are then allocated to other nodes. Following this, the game and reformation processes occur. The resource threshold for reformation is fixed at θ = 0 . 5. (b) In the UV model, the prime node remains fixed, but the threshold θ fluctuates randomly, following an AR(1) process.
