WebThe (single-site) Glauber dynamics for π is a reversible Markov chain with state space Ω, stationary distribution π, and the transition probabilities we describe below. In words, the Glauber chain moves from statexas follows: a vertexvis chosen uniformly at random fromV, and a new state is chosen according to the measure. In statistical physics, Glauber dynamics is a way to simulate the Ising model (a model of magnetism) on a computer. It is a type of Markov Chain Monte Carlo algorithm.
