Computation of Cournot–Nash Equilibria by Entropic Regularization



We consider a class of games with continuum of players where equilibria can be obtained by the minimization of a certain functional related to optimal transport as emphasized in Blanchet and Carlier (Math. Oper. Res. 41, 125–145, 2016). We then use the powerful entropic regularization technique to approximate the problem and solve it numerically in various cases. We also consider the extension to some models with several populations of players.
