WebA central idea in the algorithms we describe is the use of combinatorial algorithms other than max-product BP. This idea is closely related to earlier work on the use of combinatorial algorithms within belief propagation, either for the MAP inference problem (Duchi, Tarlow, Elidan, & Koller, 2007), or for computing marginals (Smith & Eisner, 2008).

Lagrangian relaxation is based upon the observation that many difficult integer programming problems can be modeled as a relatively easy problem complicated by a set of side constraints. To exploit this observation, we create a Lagrangian prob lem in which the complicating constraints
