Prisoner's dilemma games on a lattice

Abstract:
The iterated Prisoner's dilemma game model is simulated on two-dimensional lattice with diffusion. Complex spatial structures are composed of compact domains of cooperators separated by defector "grain boundaries". Phase ransition from defective to mixed (collaborative-defective) regime is found when increasing the diffusion constant.
