We address the following mechanism design problem: Given a multi-player Normal-Form Game with a continuous action space, find a non-discriminatory (i.e., identical for all players) restriction of the action space which maximizes the resulting Nash Equilibrium w.r.t. a social utility function. We propose the formal model of a Restricted Game and the corresponding optimization problem, and present an algorithm to find optimal non-discriminatory restrictions under some assumptions. Our experiments show that this leads to an optimized social utility of the equilibria, even when the assumptions are not guaranteed to hold.
