Drivers

Drivers repeatedly interrogate an OpenMDAO model. Generally they serve one of two purposes: optimization or design space exploration.

Optimization drivers

• ScipyOptimizeDriver

• pyOptSparseDriver

• SimpleGADriver

• DifferentialEvolutionDriver

• pymooDriver

• AnalysisDriver

• DOEDriver

Autoscalers

While some optimizers provide automatic scaling of the optimization problem, OpenMDAO itself also includes an automatic scaling capability in addition to allowing users to manually specify scaling.
