Nash Equilibrium
A core concept in game theory referring to a state in a multi-player game where no participant can improve their outcome by unilaterally changing their own strategy, given that all other participants' strategies remain unchanged.
Core Facts
Nash equilibrium refers to a situation in which, given the strategies of all other participants, no participant can obtain a better outcome by unilaterally changing their own strategy.
Nash equilibrium is a core concept in game theory proposed by mathematician John Nash.

Counterfactual regret minimization (CFR) is an iterative algorithm that approximates a Nash equilibrium by minimizing counterfactual regret and has become the mainstream solution method for games with incomplete information such as Texas Hold'em.
A pure-strategy equilibrium is a basic concept in game theory, referring to a state in which, after all players have chosen a strategy, no party can benefit by unilaterally changing its strategy—that is, a Nash equilibrium.
R-NaD introduces a regularization term into the training objective to provide a mathematically guaranteed convergence direction for policy evolution, enabling the self-play process to stably approximate a Nash equilibrium.
Competitive pressures in the AI field follow the logic of a prisoner's dilemma: even though cooperating to slow down is the globally optimal solution, the lack of mutual trust and binding enforcement mechanisms leads each rational individual to choose to accelerate their participation.
In perfect-information zero-sum games, self-play can be proven to converge to a Nash equilibrium strategy.
