The Cournot adjustment model, initial proposed by Augustin Cournot within the context of a duopoly, has players choose methods sequentially. In every amount, a firm selects the action that's its best response to the action chosen by the competing firm within the previous amount. Cournot noted that this method converges to the Nash equilibrium in some duopoly games during which corporations sequentially choose output. Cournot learning may be seen as an extreme style of fictitious play that|during which|within which} every firm assumes that its competitor is using identical strategy in each amount which is corresponding to the one most recently used.
