Constructor Detail

• EvaluationRmsChecker

  public EvaluationRmsChecker(double tol)

  Create a convergence checker for the RMS with the same relative and absolute tolerance.

  Convenience constructor for when the relative and absolute tolerances are the same. Same as new EvaluationRmsChecker(tol, tol).

  Parameters:

  tol - the relative and absolute tolerance.

• EvaluationRmsChecker

  public EvaluationRmsChecker(double relTol,
                      double absTol)

  Create a convergence checker for the RMS with a relative and absolute tolerance.

  The optimization has converged when the RMS of consecutive evaluations are equal to within the given relative tolerance or absolute tolerance.

  Parameters:

  relTol - the relative tolerance.

  absTol - the absolute tolerance.

Method Detail

• converged

  public boolean converged(int iteration,
                  LeastSquaresProblem.Evaluation previous,
                  LeastSquaresProblem.Evaluation current)

  Check if the optimization algorithm has converged.

  Specified by:

  converged in interface ConvergenceChecker<LeastSquaresProblem.Evaluation>

  Parameters:

  iteration - Current iteration.

  previous - Best point in the previous iteration.

  current - Best point in the current iteration.

  Returns:

  true if the algorithm is considered to have converged.
