In an attempt to improve on the Metropolis algorithm, various MCMC methods involving pools of proposals, such as the multiple-try Metropolis and delayed rejection strategies, have been proposed. These methods generate several candidates in a single iteration; accordingly they are computationally more intensive than the Metropolis algorithm. In this paper, we consider three samplers with pools o...

It is illustrated for 4D SU(2) lattice gauge theory that sampling with a biased Metropolis scheme is essentially equivalent to using the heatbath algorithm. Only, the biased Metropolis method can also be applied when an efficient heatbath algorithm does not exist. Other cases for which the use of the biased Metropolis-heatbath algorithm is beneficial are briefly summarized.
