= Single Objective Test Function =
The wiki page [[TestFunctions]] gives an overview of the real valued test functions available in HeuristicLab 3. The default configuration is a 2-dimensional Ackley function. 

'''Problem Parameters:'''
||= Parameter         =||= Description =||
|| !BestKnownQuality   || The quality of the best known solution of this test function. (Default: 0) ||
|| !BestKnownSolution  || The best known solution for this test function instance. (Default: {{{[0,0]]}}} ||
|| Bounds || ISingleObjectiveTestFunctionProblemEvaluator: The lower and upper bounds in each dimension. (Default: {{{[[-32,768, 32,768]]}}} || 
|| Evaluator           || The operator which should be used to evaluate  solutions. (Default: !AckleyEvaluator) ||
|| Maximization        || Set to false as most test functions are minimization problems. ||
|| !ProblemSize || The dimension of the problem. ||
|| !SolutionCreator || !UniformRandomRealVectorCreator: The operator which should be used to create new test function solutions. ||

'''Is there a sample/tutorial?'''

Yes, two actually: 
 * [[UsersSamples#SARastrigin| Rastrigin + Simulated Annealing]]
 * [[UsersSamples#ESGriewank| Griewank + Evolution Strategy]]
