The Nash equilibrium is a decision-making theorem within game theory that states a player can achieve the desired outcome by not deviating from their initial strategy. In the Nash equilibrium, each player's strategy is optimal when considering the decisions of other players. Every player wins because everyone gets the outcome they desire.

Nash equilibrium is one of the fundamental concepts in game theory. It conceptualizes the behavior and interactions Interpersonal Skills Interpersonal skills are the skills required to effectively communicate, interact, and work with individuals and groups.
Thus, the scenario when both companies advertise their products is a Nash equilibrium. Under some circumstances, a game may feature multiple Nash equilibria. John and Sam are registering for the new semester. They both have the option to choose either a finance course or a psychology course.
Nash equilibrium was discovered by American mathematician, John Nash. He was awarded the Nobel Prize in Economics in 1994 for his contributions to the development of game theory.

The Nash equilibrium is a decision-making theorem within game theory that states a player can achieve the desired outcome by not deviating from their initial strategy. In the Nash equilibrium, each player's strategy is optimal when considering the decisions of other players.
Nash Equilibrium is an outcome reached that, once achieved, means no player can increase payoff by changing decisions unilaterally. It can also be thought of as "no regrets," in the sense that once a decision is made, the player will have no regrets concerning decisions considering the consequences.
Applied to the real world, economists use the Nash equilibrium to predict how companies will respond to their competitors' prices. Two large companies setting pricing strategies to compete against each other will probably squeeze customers harder than they could if they each faced thousands of competitors.
According to game theory, the dominant strategy is the optimal move for an individual regardless of how other players act. A Nash equilibrium describes the optimal state of the game where both players make optimal moves but now consider the moves of their opponent.

Nash Equilibrium represents an action profile for all players in a game and is used to predict the outcome of their decision-making interaction. It models a steady state (i.e., a combination of strategies of all players) in which no player can benefit by unilaterally changing its strategy.
In game theory, a Nash equilibrium is an array of strategies, one for each player, such that no player can obtain a. higher payoff by switching to a different strategy while. the strategies of all other players are held fixed.
Nash equilibrium – definition Nash equilibrium, named after American Economist John Nash (1928-2015) is a solution to a non-cooperative game where players, knowing the playing strategies of their opponents, have no incentive to change their strategy.
