Game Theory
Game theory is the mathematical study of strategic interaction among agents whose outcomes depend on one another's decisions.
Overview
At a Nash equilibrium, no player improves their expected payoff by changing strategy alone while others keep theirs. Games with finitely many players and pure strategies have a possibly mixed equilibrium. Existence does not guarantee uniqueness, convergence of play, or the best collective outcome.
Why it matters
Its framework extends across disciplines: evolutionary game theory examines cooperation and stable strategies in biology, while mechanism design structures incentives to achieve intended collective outcomes in economic and computational settings. These models continue to inform theoretical analyses of strategic choice, institutions, and multi-agent coordination.
