- Method Detail
  - getPenalty
```
int getPenalty(Vertex start,
               Vertex end)
```
    Returns the penalty between two vertices.
    
    Parameters:
    
    start - the start vertex
    
    end - the end vertex
    
    Returns:
    
    the penalty between two vertices, or 0 if no single edge between the two vertices exists.
  - getDestinations
```
java.util.Iterator getDestinations(Vertex origin)
```
    Returns an iterator over all valid destinations for a given vertex.
    
    Parameters:
    
    origin - the origin from which to search for destinations
    
    Returns:
    
    the iterator over all valid destinations for a given vertex
