Webb1 okt. 2016 · We examine the stationary distribution of random walks on directed graphs. In particular, we focus on the principal ratio, which is the ratio of maximum to minimum values of vertices in the stationary distribution.We give an upper bound for this ratio over all strongly connected graphs on n vertices. We characterize all graphs achieving the … Webb1 aug. 2024 · In this algorithm after computing the transition matrix ,we should compute the stationary distribution of the random walk.

I.e., a vector u with nonnegative … Webbwalk, the whole history of the random walk path can be leveraged. Although being non-Markovian, it can be used to approximate high-order PageRanks [7, 2]. Second, as the stationary distribution of each random walk path can be guaranteed, we do not need to worry about the stationary distributions of hitting and commuting times.
