👉 Enemies in game theory, particularly within the context of non-cooperative games and computational models, refer to the strategies or actions that a rational player (the enemy) might adopt to maximize their own payoff at the expense of the other player (the main player). These enemies are typically assumed to be perfectly rational and have complete knowledge of the game's rules and the main player's preferences. In computational terms, enemies can be modeled using algorithms that predict and counter the main player's moves, aiming to minimize the main player's expected utility. This concept is crucial in understanding strategic interactions and developing optimal response strategies, such as in Nash equilibria where both players' strategies are optimal given the other's strategy.
