- Method Detail
  - 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
