WebMixing Plots. The asymptotics function returns the mixing time of a Markov chain. However, but the hitprob and hittime functions enable you to visualize the mixing by plotting hitting probabilities and expected first hitting times in a digraph.. hitprob computes the probability of hitting a specified subset of target states, beginning from each state in the … Web13 apr. 2024 · For HMC, we start from an initial 75k-step long chain (which we then discard as burn-in), and run 4 independent Markov chains each 100k-step long. For both COUS and HMC, the chains appear to be sufficiently long to ensure good mixing.

It turns out that running a local averaging algorithm is the same as following the evolution of the distribution of a certain Markov chain (see [10] ).

Web7 jun. 2024 · Couplings. One extremely cool way of finding mixing times is known as the coupling method. Couplings were invented in 1936 by the 21-year-old mathematician Wolfgang Doeblin, a man I am shocked I’d never heard of before writing this post. Wolfgang was born in Germany, but his Jewish family moved to France in 1933.
