= External Evaluation Problem = External evaluation problems can be used to optimize problems written in a language other than C# or written using different framework such as simulation models. '''Tutorial''': The [http://cig.dei.polimi.it/?page_id=103 Race Car Setup Optimization Competition] was organized for the [http://dces.essex.ac.uk/research/evostar/ EvoStar 2010] conference. The problem is a classic "simulation-based optimization problem" with a simulator, a simulation model, and several configuration parameters that have to be optimized. The following [[DevelopersOptimizingExternalApplications| Tutorial]] will show you how to configure an external evaluation problem for that particular problem.
