Abstract : This paper present recurrence formulas allowing the calculus of the marginals and the normalizing constant of a Gibbs distribution π.The numerical performances of different methods are evaluated on several examples, particularly for an Ising model on a lattice.


Keywords : Ising model Gibbs distribution factorisable distribution interaction potential Markov Chain Markov field marginal law normalizing constant Ising model.
