... (randomized) algorithm for exact mixing in an unknown chain has now been devised by J.G. Propp and D.B. Wilson, using the elegant notion of “coupling from the past.” Their stopping rule runs in ... achieved in a time O(T mix ), which is typically polylogarithmic in h. But this shortcoming of our algorithm cannot be fixed; we will show that mixing in an unknown Markov ch...

It follows that the electronic journal of combinatorics 11 (2004), #R18 10 Equilateral Triangles in Finite Metric ... In the following we will talk about metric spaces with distances in sets not containing 0: this slight abuse of language is only meant to simplify the discourse, since while 0...
