Web19 sep. 2024 · The -th power of the adjacency matrix of a simple undirected graph represents the number of walks with length between pairs of nodes. As a walk where no node repeats, a path is a walk where each node is only visited once. The set of paths constitutes a relatively small subset of all possible walks.
