Fastest mixing markov chain
WebMixing times via super-fast coupling 2 1 Introduction. Random shufflings of a deck of n distinct cards are well-studied objects and a frequent metaphor describing a class of Markov chains invariant with respect to the symmetric group, S n. Here the focus is on transposition shuffling, one of the simplest shuffles, defined by WebAug 9, 2004 · The FDC problem (2) is closely related to the problem of finding the fastest mixing Markov chain on a graph [3]; the only difference in the two problem formulations is that in the FDC problem, the ...

Webthe fastest mixing Markov chain to those obtained using two commonly used heuristics: the maximum-degree method, and the Metropolis-Hastings algorithm. For many of the examples considered, the fastest mixing Markov chain is substantially faster than those obtained using these heuristic methods. WebFASTEST-MIXING MARKOV CHAINS 1 779 allowed only along the edges in E. This is a very important problem because of the use of Markov chains in Markov chain Monte Carlo (MCMC), where the goal is to sample (at least approximately) from n and the Markov chain is con-structed only to facilitate generation of such observations as efficiently as possible.

Create a 23-state Markov chain from a random transition matrix containing 250 infeasible transitions of 529 total transitions. An infeasible transition is a transition whose probability of occurring is zero. Plot a digraph of the Markov chain and identify classes by using node colors and markers.
