What is Game Theory and why is it important?
Updated May 16, 2026
Short answer
Game Theory is the study of strategic decision-making where outcomes depend on multiple interacting agents.
Deep explanation
Game Theory analyzes how rational players make decisions in competitive or cooperative environments. Each player's payoff depends not only on their own actions but also on the actions of others. It is widely used in economics, AI, auctions, and network systems to model strategic behavior.
Real-world example
Used in pricing strategies where companies adjust prices based on competitor behavior.
