  - evaluate
```
double evaluate(double[] argument)
```
    compute function value
    
    Parameters:
    
    argument - function argument (vector)
    
    Returns:
    
    function value
  - getNumArguments
```
int getNumArguments()
```
    get number of arguments
    
    Returns:
    
    number of arguments
  - getLowerBound
```
double getLowerBound(int n)
```
    get lower bound of argument n
    
    Parameters:
    
    n - argument number
    
    Returns:
    
    lower bound
  - getUpperBound
```
double getUpperBound(int n)
```
    get upper bound of argument n
    
    Parameters:
    
    n - argument number
    
    Returns:
    
    upper bound
  - getOrthogonalHints
```
OrthogonalHints getOrthogonalHints()
```
    Returns:
    
    an Orthogonal Hints object that can be used by Orthogonal based optimisers to get information about the function
