public class Beale extends AbstractProblem
The single-objective Beale problem with an optimum at x = (3.0, 0.5) with f(x) = 0.

  • Constructor Details

    • Beale

      public Beale()
      Constructs a new instance of the Beale problem.

  • 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

    • newSolution

      public Solution newSolution()
      Description copied from interface: Problem
      Returns a new solution for this problem. Implementations must initialize the variables so that the valid range of values is defined, but typically leave the actual value at a default or undefined state.
      Returns:
      a new solution for this problem

    • getReferenceSet

      public NondominatedPopulation getReferenceSet()
      Returns the reference set, typically a single solution unless the problem has multiple local minima, for this single objective problem.
      Returns:
      the reference set
