Nash equilibrium a nash equilibrium of a strategic game is a profile of strategies (s_1^ ,s_n^) , where s_i^ in s_i ( s_i is the strategy set of player i ), such that for each player i , forall s_i in s_i , u_i(s_i^,s_(-i)^)= , where s_(-i)=(s)_(j in n\{ and u_i:s=×_(j in n)s_j-r another way to state the nash equilibrium.

A nash equilibrium is a set of strategies that players act out, with the property that no player benefits from changing their strategy intuitively, this means that if any given player were told the strategies of all their opponents, they still would choose to retain their original strategy for example, in the game of trying to guess 2/3.

Sufficient conditions for nash equilibrium in an n-person game are given in terms of what the players know and believe-about the game, and about each other's rationality, actions, knowledge, and beliefs mixed strategies are treated not as conscious randomiza- tions, but as conjectures, on the part of other players, as to.

Several works have recently modelled the problem as a game, and thus proposed algorithms to coordinate the vehicles towards a nash equilibrium however, nash equilibria have been shown to posses desirable system-level properties only in simplified cases, and it is unclear to what extent these results.

Allowing mixed strategies (u,v), in three dimensions, a smooth regular parameterized manifold of outcomes x = (x(u,v), y(u,v), z(u,v)) all of which are nash equilibria may form a minimal surface if one is interested in minimizing tension between players, or what is the same, may form a vanishing mean curvature flow of play.
