What is a saddle point in game theory?
A necessary and sufficient condition for a saddle point to exist is the presence of a payoff matrix element which is both a minimum of its row and a maximum of its column. A game may have more than one saddle point, but all must have the same value. SEE ALSO: Game, Payoff Matrix, Value.
Given a matrix of n x n size, the task is to find saddle point of the matrix. A saddle point is an element of the matrix such that it is the minimum element in its row and maximum in its column.
- Any saddle that doesn't have a rigid tree is really just a glorified bareback pad.” Argo pointed out that a traditional saddle is more forgiving of the rider. “People using treeless saddles say that they can feel all the horse's movements, but then the opposite is also true – the horse feels all your movements.
- A good gullet height is between two and four finger's width between your horse's withers and the saddle fork. You should be able to see the tunnel in between the two.

If a critical point is not stable then it is unstable. In the figure above we see that a center is stable but not asymptotically stable, that a saddle point is unstable, that a node is either asymptotically stable (sink) or unstable (source) and that a spiral either is asymptotically stable or unstable.
- It is a two-dimensional case of the general n-dimensional phase space. The phase plane method refers to graphically determining the existence of limit cycles in the solutions of the differential equation. Graphically, this can be plotted in the phase plane like a two-dimensional vector field.
- These economic variables remain unchanged from their equilibrium values in the absence of external influences. Economic equilibrium may also be defined as the point at which supply equals demand for a product, with the equilibrium price existing where the hypothetical supply and demand curves intersect.
- Definition of nullcline. The x-nullcline is a set of points in the phase plane so that dx dt = 0. Geometrically, these are the points where the vectors are either straight up or straight down. Alge- braically, we find the x-nullcline by solving f(x, y)=0. The y-nullcline is a set of points in the phase plane so that.
Game Saddle Point. A necessary and sufficient condition for a saddle point to exist is the presence of a payoff matrix element which is both a minimum of its row and a maximum of its column. A game may have more than one saddle point, but all must have the same value.
- In game theory, a player's strategy is any of the options he or she can choose in a setting where the outcome depends not only on his own actions but on the action of others. A player's strategy will determine the action the player will take at any stage of the game.
- Payoff. In any game, payoffs are numbers which represent the motivations of players. Payoffs may represent profit, quantity, "utility," or other continuous measures (cardinal payoffs), or may simply rank the desirability of outcomes (ordinal payoffs).
- Game theory is the study of how and why people make decisions. (Specifically, it is "the study of mathematical models of conflict and cooperation between intelligent rational decision-makers".) It helps people understand parts of science and politics.
