Stable matching is a fundamental concept in game theory and economics, where the goal is to pair elements of two sets based on preferences, ensuring no two elements would prefer each other over their current match. The Gale-Shapley algorithm famously solves this problem, guaranteeing a stable matching where no pair has an incentive to deviate from their assigned match.

Game theory is a mathematical framework used for analyzing strategic interactions where the outcome for each participant depends on the actions of all involved. It provides insights into competitive and cooperative behaviors in economics, politics, and beyond, helping to predict and explain decision-making processes in complex scenarios.

Economics is the study of how individuals, businesses, and governments make choices on allocating resources to satisfy their wants and needs, and how these choices interact to shape markets and economies. It encompasses both microeconomic and macroeconomic perspectives, analyzing everything from individual consumer behavior to global economic trends.

Preferences are the subjective tastes and priorities that individuals or groups have regarding choices or outcomes. They influence decision-making processes and can be shaped by factors such as cultural background, personal experiences, and psychological traits.

The Gale-Shapley algorithm, also known as the Deferred Acceptance algorithm, is a fundamental solution to the stable marriage problem that ensures a stable matching between two equally sized sets of participants. It guarantees that no pair of participants would prefer each other over their current partners, thus preventing any instability in the matching process.
