Thank you all for the reply,
In response to Walter, for instance, if I have paths following a square figure with a diagonal in the middle, there will be 3 ways to go from point A to points C.
So if I input AllPaths(nodeset, pathset, A, C), the function that I looked for should output:
1. A B C
2. A C
3. A D C
I am not certain about that centrality function, would it be helpful for this kind of example. Any suggestions would be much appreciated. Thank you.
