In mathematics, a saddle point or minimax point 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. 在数学中,鞍点或极小值点是函数图形表面上的一...

: a point on a curved surface at which the curvatures in two mutually perpendicular planes are of opposite signs compare anticlastic 2 : a value of a function of two variables which is a maximum with respect to one and a minimum with respect to the other The...
Answer to: Find the relative extrema and saddle points of the function. A) f(x, y) = x^4 + y^4 - 4xy + 1 B) f(x, y) = (x^2 + y^2)(e^(-x)) By...
The locations of the maximums, minimums and saddle points of a function are the critical points. To find the critical points of a function f(x,y) we generate a system of equations in which each partial derivative is set equal to 0. The solutions to the system are...
Decomposition methods for finding saddle points of a function φ:X × Y → ℝ are characterized by an alternating succession of master programs and subprograms [7]. The master programs determine the proper iteration points, which are approximate saddle points over a subset Xn× Yn of the origi...

It is shown that a saddle point ( z , λ ) of a certain function gives a uniform norm solution, z , of Az = b and a weight vector λ of the equivalent weighted l p norm problem. With appropriate qualifications concerning the weights, it follows that the worst (i.e., largest) ...
