網頁Gibbs sampling is a special case of the Metropolis-Hastings algorithm, invented to simulate complex systems in solid-state physics (Metropolis et. al, 1953). The name comes from by Geman and Geman’s 1984 paper, which offered the algorithm as a particular case of the Gibbs distribution. It was developed to reconstruct a noisy image (Bolstad ... 網頁The chain {X (i))~-1 induced by the random scan Gibbs sampler is Markov with invariant distribution 7r.
