Perfect simulation refers to the art of converting suitable Markov Chain Monte Carlo algorithms into algorithms which return exact draws from the target distribution, instead of approximations based on long-time convergence to equilibrium. The theoretical concepts underlying perfect simulation have a long history, but they were first drawn together to form a practical simulation technique in the ground-breaking paper of Propp and Wilson [78], which showed how (for example) to obtain exact draws from the critical Ising model on a finite lattice. These lecture notes are organized around four main themes of perfect simulation: the original or classic Coupling From The Past algorithm (CFTP); variations which exploit regeneration ideas such as small-set or split-chain constructions from Markov chain theory (small-set CFTP); generalizations of CFTP which deal with non-monotonic and non-uniformly ergodic examples (dominated CFTP); and finally some theoretical complements.
