## Optimizer

The SUMO Toolbox contains a whole hierarchy of optimizers that can be used by several components (for instance the InfillSamplingCriterion). Currently the following optimization methods are supported:

### DirectOptimizer

DIviding RECTangles is a global optimization algorithm based on the divide & conqueror philosophy. It is quite efficient at finding accurate, global optimums of computationel cheap functions. It is one of the standard choices to optimize the expected improvement function.

### MatlabOptimizer

This optimizer is a wrapper around Matlab's own optimization methods: fminunc and fmincon.
