Nash equilibrium is an outcome of a game such that no player can gain by unilaterally changing its strategy. It is achieved when each player adopts the optimal strategy given the strategy of the other player.
In this section, the formal definition of a Nash equilibrium is first introduced. With this definition, an application of the optimality condition leads to that a problem has a Nash equilibrium if and only if system (2.1) has a solution. After exploiting the properties of pure strategy and mu...
Nash equilibrium occurs when each player is seeking his or her best possible strategy, while fully aware of the strategies that everybody else is pursuing.
A basic definition is this: If there is a set of strategies for a game with the property that no player can benefit by changing his strategy while the other players keep their strategies unchanged, then that set of strategies and the corresponding payoffs constitute a Nash equilibrium....
