Belief propagation, via a novel reinterpretation of the Bethe free energy's pseudo-dual, is shown to be related to a novel relaxation of maximum likelihood detection via a constrained optimization. The conventional maximum likelihood detection falls out for a zero constraint, and belief propagation's fixed points are obtained for other constraint values.
