Method Details
- getEvaluations
  
  int getEvaluations()
  
  Get the number of times the model was evaluated in order to produce this optimum.
  
  Returns:
  
  the number of model (objective) function evaluations
- getIterations
  
  int getIterations()
  
  Get the number of times the algorithm iterated in order to produce this optimum. In general least squares it is common to have one evaluation per iterations.
  
  Returns:
  
  the number of iterations
