Class Rastrigin

All Implemented Interfaces:
Function<Vector,Double>, RealScalarFunction

public class Rastrigin extends AbstractRealScalarFunction
The Rastrigin function is a non-convex function used as a performance test problem for optimization algorithms. It is a typical example of non-linear multimodal function. Finding the minimum of this function is a fairly difficult problem due to its large search space and its large number of local minima.
