Webbtransition matrix for a reversible Markov chain with stationary distribution ˇ. For any vertex in group i, the label of a uniformly random neighbor is roughly distributed according to the ith row of T, and, more generally, the vertex labels encountered by a random non-backtracking random walk are approximately governed Webb2.2. Transition Probabilities. When a discrete random walk process is running on a single layer network, at each time step a walker is on a node and moves to a node chosen randomly and uniformly among its neighbours. The sequence of visited nodes is a Markov chain, whose states are the nodes of the graph. As for the multi-layer network, the random
