- Method Detail
  - fixVariable
```
default boolean fixVariable(int index,
                            double value)
```
    Parameters:
    
    index - The, solver specific, variable index
    
    value - The value to fix that variable to
    
    Returns:
    
    true if fixing is supported and was successful, otherwise false
  - generateCutCandidates
```
default java.util.Collection<Equation> generateCutCandidates(double fractionality,
                                                             boolean... integer)
```
  - getEntityMap
```
ExpressionsBasedModel.EntityMap getEntityMap()
```
  - integers
```
default boolean[] integers(ExpressionsBasedModel model)
```
  - isMapped
```
default boolean isMapped()
```
  - updateRange
```
default boolean updateRange(int index,
                            double lower,
                            double upper)
```
    A generalisation of fixVariable(int, double) where the new/updated lower and upper bounds do not need to be equal.
    
    Parameters:
    
    index - The, solver specific, variable index
    
    lower - New lower bound
    
    upper - New upper bound
    
    Returns:
    
    true if updating the range is supported and was successful, otherwise false
