GibbsSampler

class GibbsSampler extends ProposalSampler[Var]

Sample a value for a single variable. This sampler works in one of two ways: If the model is a DirectedModel, then sampling is performed based on a suite a handlers selected according to the variable type and its neighboring factors. If the model is not a DirectedModel, then the variable should inherit from IterableSettings which is used to create a list of Proposals with alternative values.
