The iterated Prisoner's Dilemma in societies of deterministic players

Two players engaged in the Prisoner’s Dilemma have to choose between cooperation and defection, the pay-off of the players is determined by a weight w=(T ,R ,P ,S ) . For deterministic strategies p 1 ,... , p n we consider a society S=S( u i : p i∣ i=1 ,... ,n) formed by individuals playing at random the IPD with weight w . We introduce the concept of a w -successful society as one where all individuals have eventually a non-negative pay-off. We discuss success of individuals and societies by means of quadratic forms associated to the pay-off matrix of the given set of strategies.
