Typically, only the shortest paths are considered in the definition of betweenness. However, there are a couple issues with this approach:

- All paths (even slightly) longer than the shortest ones are not considered.
- The actual number of shortest paths that lie between the two nodes is irrelevant.

In many applications, however, it is reasonable to consider both the quantity and the length of *all* paths of the network, since communication on the network is enhanced as soon as more routes are possible, particularly if these pathways are short.

Which of the following is *not* an issue of shortest path betweenness?
