Class Rastrigin

All Implemented Interfaces:
AutoCloseable, Problem

public class Rastrigin extends BBOBFunction
The Rastrigin function. For a problem with D variables, this highly multimodal function has approximately 10^D local optima. It is not intended for this function to be used directly since the BBOB test suite applies additional transformations to the test functions.

Properties:

  • Separable
  • Multimodal
  • Constructor Details

    • Rastrigin

      public Rastrigin(int numberOfVariables)
      Constructs a new instance of the Rastrigin function.
      Parameters:
      numberOfVariables - the number of decision variables
  • Method Details

    • evaluate

      public void evaluate(Solution solution)
      Description copied from interface: Problem
      Evaluates the solution, updating the solution's objectives in place. Algorithms must explicitly call this method when appropriate to evaluate new solutions or reevaluate modified solutions.
      Parameters:
      solution - the solution to be evaluated
