... take any point a ∈ A. There are three cases. If a ∈ B, then f (a) and h(a) both belong to I1 ; if a ∈ C, then f (a) and h(a) both belong to I3 ; if a �∈ B ∪ C, then f (a) and h(a) both belong to I2 . In each case, the distance between f (a) and h(a) can be at most 23 r, which proves (15.5). The seco ...

... Now to find the critical values we compute where Df (x, y) = (0, 0) We easily find the following points (0, 0), (1, −1), and (1/2, −3/8). Now using our criteria on each of these points we find that the points (0, 0) and (1, −1) are both saddle points, while (1/2, −3/8) is a local minimum. 5. Let F(x ...

Mathematical optimization
In mathematics, computer science and operations research, mathematical optimization (alternatively, optimization or mathematical programming) is the selection of a best element (with regard to some criteria) from some set of available alternatives.In the simplest case, an optimization problem consists of maximizing or minimizing a real function by systematically choosing input values from within an allowed set and computing the value of the function. The generalization of optimization theory and techniques to other formulations comprises a large area of applied mathematics. More generally, optimization includes finding ""best available"" values of some objective function given a defined domain (or a set of constraints), including a variety of different types of objective functions and different types of domains.
