-	<p>The optimization has to be properly configured by selecting the modules as illustrated.

+	In this example, we optimize a single objective which are the costs.
 	It is possible to implement any kind of evaluator, including non-linear objectives. 
 	Furthermore, it is possible to use external evaluators, i.e., programs that receive the respective implementation as XML and return their result as XML. </p>
