Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`int`	`getInternalParameterBoundaries(int parameter, double[] storage)`	A boundary is a value of a parameter for which values lower than the boundary and values higher than the boundary are better treated as two separate functions (IE, they are only piecewise connected), and minimisation should be performed over both ranges individually (and then the true minimum taken as the minimuma of the ranges)
`OrderEnumerator`	`getSuggestedOrdering(OrderEnumerator defaultOrdering)`	If there is a "best" ordering to use it can be specified here, if not should return null

- Method Detail
  - getSuggestedOrdering
```
OrderEnumerator getSuggestedOrdering(OrderEnumerator defaultOrdering)
```
    If there is a "best" ordering to use it can be specified here, if not should return null
    
    Parameters:
    
    defaultOrdering - The ordering suggested by the optimiser, may be null!
    
    Returns:
    
    null, or default ordering if no known best ordering
  - getInternalParameterBoundaries
```
int getInternalParameterBoundaries(int parameter,
                                   double[] storage)
```
    A boundary is a value of a parameter for which values lower than the boundary and values higher than the boundary are better treated as two separate functions (IE, they are only piecewise connected), and minimisation should be performed over both ranges individually (and then the true minimum taken as the minimuma of the ranges)
    
    Returns:
    
    the number of boundary locations stored in storage, or -1 if not enough room, or 0 if there are no boundaries (other than the normal parameter range)
