support_enumeration
(g)[source]¶ Compute mixedaction Nash equilibria with equal support size for a 2player normal form game by support enumeration. For a nondegenerate game input, these are all the Nash equilibria.
The algorithm checks all the equalsize support pairs; if the players have the same number n of actions, there are 2n choose n minus 1 such pairs. This should thus be used only for small games.
Parameters:  g : NormalFormGame
NormalFormGame instance with 2 players.
Returns:  list(tuple(ndarray(float, ndim=1)))
List containing tuples of Nash equilibrium mixed actions.
