The parameters of the Ising model are specified in the function setup_model.m. The various samplers can be run using test_(name-of-sampler).m. Please bear in mind that this is research code and that we have experimented with various different settings for the D&C-SMC methodology. This is the reason for why a large number of parameters can be specified by the user, affecting the properties of the sampler in different ways as explained in the code.
