mittekoostöömängudeks

Mittekoostöömängudeks are a class of games in game theory where players cannot form binding agreements or commitments. In these games, each player acts independently, pursuing their own self-interest without the ability to coordinate actions with others. The outcome for each player depends not only on their own choices but also on the choices of all other players. The absence of cooperation means that strategies that might be mutually beneficial if agreed upon cannot be reliably executed.

The concept of non-cooperative games is fundamental to understanding strategic interactions in various fields, including economics, political science, and evolutionary biology. A key concept within non-cooperative game theory is the Nash equilibrium. A Nash equilibrium is a state where no player can improve their outcome by unilaterally changing their strategy, assuming the other players' strategies remain unchanged. This equilibrium represents a stable point in the game, even in the absence of communication or trust between players.

Examples of non-cooperative games include the Prisoner's Dilemma, where individual rationality leads to a suboptimal outcome for both players, and the Stag Hunt, which illustrates the conflict between safety and mutual gain. The analysis of these games helps to explain why cooperation can be difficult to achieve and how strategic thinking under conditions of self-interest can lead to predictable outcomes. The focus is on predicting individual behavior and the resulting state of the system.
