Contingent Movement Rules in the Evolution of Cooperation

In this model, there are 4 types of agents, cooperators with contingent movement rules, defectors with contingent movement rules, cooperators without contingent movement and defectors without contingent movement.  Cooperators with contingent movement always cooperate, but if their partner defects, they move on the next turn.  Defectors with these movement rules do the same thing, but they always defect.  The cooperators and defectors without movement rules also use pure strategies (always cooperate and always defect) but they do not move once they find a partner, no matter what that partner does.
