Finding the partition function z of a probability, Ask an Expert

Academics

Finding the partition function Z of a probability distribution is a difficult problem. Many Markov chain Monte Carlo methods produce valid samples from a distribution without ever finding out what Z is. Is there any probability distribution and Markov chain such that either the time taken to produce a perfect sample or the number of random bits used to create a perfect sample are related to the value of Z? Are there some situations in which the time to coalescence conveys information about Z?
