Quizplus · Accepted Answer

In game theory, an outcome can be ruled out if one player would want to change their strategy because it implies that the outcome is not a Nash Equilibrium. A Nash Equilibrium occurs when no player has anything to gain by changing only their own strategy unilaterally. If one player would benefit from changing their strategy, then the current outcome cannot be stable or optimal for all players involved.
