bp()

void bp	(	struct Node **	nodes,
		int	num_nodes,
		int	num_iterations
	)

Loopy belief propagation.

Parameters

nodes	The set of nodes for which to run BP. Probably should be all nodes in the MRF.
num_nodes	The number of nodes.
num_iterations	Number of iterations for which to run loopy bp. If the graph is a tree, set to 3 for analytical results.
