Strategies for updating rules driven by reinforcement learning to solve social dilemmas
Fig 3
Shows snapshots of spatial distributions for blue cooperators and purple defectors at different MCS for various δ value.
Vertically, the diffusion of cooperative behavior accelerates with increasing δ. Simulations indicate that larger δ significantly promotes cooperation. Parameters are set to b = 1.1, α = 0.5, β = 2 and L = 200.
