Participant : Mark Schmidt [correspondant] .

The code contains implementations of several available methods for the problem of computing an approximate minimizer of the sum of a set of unary and pairwise real-valued functions over discrete variables. This equivalent to the problem of MAP estimation, also known as decoding, in a pairwise undirected graphical model. The code focuses on scenarios where the pairwise energies encourage neighboring variables to take the same state. The particular methods contained in the package are iterated conditional mode, alpha-beta swaps, alpha-expansions, and alpha-expansion beta-shrink moves.
