The article explores how players in strategic games find the best strategies to win. It shows that games can have different types of Nash equilibria, which are points where no player has an incentive to change their strategy. The researchers use examples like the Prisoners' Dilemma and Matching Pennies to explain this concept. They also discuss how some games can have many equilibria. Nash used a math theorem to prove that equilibria exist. The article also talks about ways to refine the Nash equilibrium idea. Overall, it helps us understand how players in games can make decisions to reach balanced outcomes.
