Dominant strategy

A dominant strategy in game theory is one where a single strategy is best for a player regardless of what strategy the other players in the game decide to use.

In game theory, a dominant strategy is a strategy that is the best choice for a player regardless of the strategies chosen by other players in the game. It is a strategy that guarantees the player the highest payoff or outcome, regardless of what the other players do.

For example, in rock-paper-scissors, throwing rock is not a dominant strategy because it can be beaten by paper. However, throwing scissors is a dominant strategy because it beats paper, which is the only move that beats scissors. In this case, throwing scissors is the best option for a player, regardless of what the other player chooses.

A dominant strategy eliminates the need for players to anticipate or predict the behavior of others, as it guarantees the best outcome regardless of what other players do.
