I can post literally hundreds of examples of directed graphs that are traversable in the forward direction. This might be the only one which is *only* traversable backwards.
> As to the meaning of "point to"
Here is one: If I have a pointer in memory, I might represent that with an arrow,
Like: ADDRESS -> VALUE
Or if I have a dictionary I might write:
KEY -> VALUE
But in the graph the edges are directed the opposite way:
KEY <- VALUE
The edges in the graph point in the opposite direction as the underlying memory pointers. This is unexpected and confusing. |
