Webcalled Sequential Importance Sampling (SIS) is discussed in Section 3. In the absence of a natural decomposition, it is still possible to apply the SIS framework by extending the Monte Carlo problem to an augmented space. A speci c implementation of this strategy, known as Annealed Importance Sampling is presented in Section 4. leber washout
