The evolution of cooperation is perhaps the most profound application of this field. Through "Iterated Games" (playing the same game repeatedly), players learn that long-term gains from cooperation outweigh short-term gains from betrayal. Strategies like "Tit-for-Tat"—starting with cooperation and then mimicking the opponent’s last move—have shown that simple, reciprocal interactions can lead to the evolution of complex, stable societies. Conclusion Can players make binding agreements, or is it

Do players know each other’s payoffs (Symmetric vs. Asymmetric)? The most famous model, the , illustrates the

The most famous model, the , illustrates the tension between individual and collective rationality. Two suspects are interrogated separately. If both stay silent, they get light sentences. If one betrays the other, the "snitch" goes free while the other gets a heavy sentence. If both betray each other, both get moderate sentences. Rationally, each individual is better off betraying the other, leading to a worse outcome for both than if they had cooperated. This highlights why cooperation is difficult to maintain even when it is mutually beneficial. 2. Interaction and Equilibrium

EGT introduced the concept of the . An ESS is a strategy that, if adopted by a population, cannot be invaded by a rare alternative strategy. For example, the "Hawk-Dove" game explains why animals often use display rituals rather than lethal combat; a population of "Hawks" (constant fighters) risks total injury, while a few "Doves" (retreaters) can survive and pass on their genes by avoiding the costs of war. 4.
