A saddle point (in red) on the graph of z = x 2 − y 2 (hyperbolic paraboloid). In mathematics, a saddle point or minimax point [1] is a point on the surface of the graph of a function where the slopes (derivatives) in orthogonal directions are all zero (a critical point), but which is not a local extremum of the function. [2]
Solution of zero-sum simple pursuit games such as "lifeline game", "two pursuers – one evader game", "deadline game in a half plane". Proof of the existence of an epsilon-saddle point in piecewise open loop strategies in general dynamic zero-sum games with prescribed duration and independent motions. Method of solution of pursuit games based ...
Since I is somewhat smooth, there must be a critical point somewhere in between. (Think along the lines of the mean-value theorem.) The mountain pass lies along the path that passes at the lowest elevation through the mountains. Note that this mountain pass is almost always a saddle point. For a proof, see section 8.5 of Evans.
In game theory, a strictly determined game is a two-player zero-sum game that has at least one Nash equilibrium with both players using pure strategies.The value of a strictly determined game is equal to the value of the equilibrium outcome.

The first theorem in this sense is von Neumann's minimax theorem about two-player zero-sum games published in 1928, [2] which is considered the starting point of game theory. Von Neumann is quoted as saying "As far as I can see, there could be no theory of games
In mathematics, the max–min inequality is as follows: . For any function : , (,) (,) .When equality holds one says that f, W, and Z satisfies a strong max–min property (or a saddle-point property).
