WHAT IS IT?

This model is a version of Spatialy Iterated Prisoner's Dilemma which was developed by Nowak, May and Sigmund. This represents the race of cooperator and defector in NxN lattice.

HOW IT WORKS

You can run the model with random distribution of cooperators-defectors (RANDOM-SIZER) or one defector around cooperators (ONE-RED). Every patches play games with their neighbors. Every patches get score after game. This score is the number of neighbor cooperators. The patch will be cooperator or defector due to the value of higher score neighbor. The patch can use the next colorization:

Copperation after cooperation: color blue
Cooperate after Defection: yellow
Defection after Cooperation: green
Defection after Defection: red

HOW TO USE IT

You can run TFT, PAVLOV, ALLD, GRIM strategies in this model.

THINGS TO TRY

Try different strategies together. Look the patterns.
