Open publisher page 1 citations

Abstract

Via a 2-stage linear-quadratic 2-person nonzero-sum game, we show that such decision problems might admit nonlinear Nash solutions. As compared with the linear strategy, a nonlinear Nash policy might lead to a better performance for at least one of the players.
