Abstract. Simulated annealing — moving from a tractable distribution to a distribution of interest via a sequence of intermediate distributions — has traditionally been used as an inexact method of handling isolated modes in Markov chain samplers. Here, it is shown how one can use the Markov chain transitions for such an annealing sequence to define an importance sampler. The Markov chain aspec...

Novel Coronavirus 2019 or as known COVID-19 is a new disease that caused of Severe Acute Respiarory Syndrome Coronavirus-2 (SARS-CoV-2) which found in Wuhan, China at the end year, 2019. Beside clinical characteristics based on mild until severed illness such fever, cough, loss smelling decrease lungs perfussion, another physical examination required Polymerase Chain Reaction (PCR) can be gold ...

A “lifting” of a Markov chain is a larger chain obtained by replacing each state of the original chain by a set of states, with transition probabilities defined in such a way that the lifted chain projects down exactly to the original one. It is well known that lifting can potentially speed up the mixing time substantially. Essentially all known examples of efficiently implementable liftings ha...
