Therefore, the best strategy for it is cooperation strategy, and there exists the only one Nash equilibrium (cooperation, noncooperation).
We test the Nash equilibrium prediction of these games, which is identical in all of them, under a perfect-stranger matching protocol that allows a group of paired participants to play each game only once.
1]; it can be seen that if the system is in stable condition, after a finite game the system can be stable in the Nash equilibrium, then profit of each manufacturer or retailer is stable.
After this concise and elegant definition of the equilibrium point, now known as Nash equilibrium, follows an existence proof using the Kakutani fixed-point theorem.

198) For example, there could be a mixed strategy Nash equilibrium in which the criminal innovates with a probability of one-third (and does not innovate with a probability of two-thirds), and in which LEOs investigate with a probability of three-fourths (and do not investigate with a probability of one-fourth).

Informally, a Nash equilibrium can be described as follows: If there is a set of strategies for a game with the property that no player can increase the payoff by changing its strategy while the other players keep their strategies unchanged, then that set of strategies and the corresponding payoffs constitute a Nash equilibrium.
