API¶

Optimization problems define the basic wind farm problem setup and the variables that will be modified by the optimizer. Objectives and constraints are then subsequently added to the problem. Finally, any optimizer from iwopy can be used to find optimal values of the optimization variables (or Pareto fronts).

Please consult the `iwopy documentation<https://fraunhoferiwes.github.io/iwopy.docs/index.html>`_ for details of the optimizers, and see the Examples section for applications.
