Webso the resulting Markov chain or random walk mixes as rapidly as possible. In this note we prove that fastest mixing is obtained when each edge has a transition probability of … WebIn the Fastest Mixing Markov Chain problem, we are given a graph G = (V,E) and desire the discrete-time Markov chain with smallest mixing time τ subject to having equilibrium distribution uniform on V and non-zero transition probabilities only across edges of the graph. It is well-known that the mixing time τ

Webwords, what is the fastest mixing (symmetric) Markov chain on the graph? This can be posed as the following optimization problem: minimize µ(P) subject to P ≥ 0, P1= 1, P = PT Pij = 0, {i,j} ∈ E/ . (1) Here P is the optimization variable, and the graph is the problem data. We call this problem the fastest mixing Markov chain (FMMC) problem.
