All paths of given length between two given nodes in a graph?

The solution to this problem is simple - raise the adjacency matrix to the N-th power and the answer will sit in the cell (N1, N2) for each pair N1 and N2 - basic graph theory.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
