A Linear Programming Approach to Max-Sum Problem: A Review

Abstract: The max-sum labeling problem, defined as maximizing a sum of functions of pairs of discrete variables, is a general optimization problem with numerous applications, e.g., computing MAP assignments of a Markov random field. We review a not widely known approach to the problem based on linear programming relaxation, developed by . We also show how this old approach contributes to more recent results, most importantly by Wainwright et al. In particular, we review Schlesinger's upper bound on the max-sum criterion… Show more

“…The scalars λ s and δ weigh the importance of the terms (set to 1 and 0.2 in our experiments). We perform the inference in the MRF by efficient and fast publicly available max-sum solver [29] based on linear programming relaxation and its Lagrangian dual. Figure 6 shows some examples of the proposed change detection algorithm.…”

“…It is a variational optimization algorithm designed to solve the LP-relaxation of a discrete energy minimization problem. This LP-relaxation was studied in, e.g., original paper [10], review [14]). The TRW-S algorithm has the same asymptotic behavior as algorithms in [6,14].…”

“…This LP-relaxation was studied in, e.g., original paper [10], review [14]). The TRW-S algorithm has the same asymptotic behavior as algorithms in [6,14]. It may not solve the LP-relaxation problem, since its stationary points satisfy only a necessary optimality condition (studied in [10,14,5]).…”
