Simulated Tempering and Umbrella Sampling
Markov chain Monte Carlo for continuous random vectors using parallel or serial simulated tempering, also called umbrella sampling. For serial tempering the state of the Markov chain is a pair (i, x), where i is an integer between 1 and k and x is a vector of length p. This pair is represented as a single real vector c(i, x). For parallel tempering the state of the Markov chain is vector of vectors (x[1], …, x[k]), where each x is of length p. This vector of vectors is represented as a k by p matrix.
