Template:No footnotes Global optimization is a branch of applied mathematics and numerical analysis that deals with the optimization of a function or a set of functions according to some criteria. Typically, a set of bound and more general constraints is also present, and the decision variables are optimized considering also the constraints.

General

A common (standard) model form is the minimization of one real-valued function in the parameter-space , or its specified subset : here denotes the set defined by the constraints.

(The maximization of a real-valued function is equivalent to the minimization of the function .)

In many nonlinear optimization problems, the objective function has a large number of local minima and maxima. Finding an arbitrary local optimum is relatively straightforward by using classical local optimization methods. Finding the global minimum (or maximum) of a function is far more difficult: symbolic (analytical) methods are frequently not applicable, and the use of numerical solution strategies often leads to very hard challenges.

Applications of global optimization

Typical examples of global optimization applications include:

Approaches

Deterministic methods

The most successful general strategies are:

Stochastic methods
