چکیده
• And we need to adapt the BP equations to cope with (-1). • Standard BP equations can be derived as stationary point conditions for continuous constrained optimization problem [Yedidia et al. ‘05] • Let p(x) be the uniform distribution over solutions of a problem • Let b(x) be a unknown parameterized distribution from a certain family • The goal is to minimize DKL(b||p) over parameters of b(.) • Use b(.) to approximate answers about p(.) • The BP adaptation for Z(-1) follows exactly the same path, and generalizes where necessary.

A Spectral Approach to Analysing Belief Propagation for 3-Colouring
Belief Propagation (BP) is a message-passing algorithm that computes the exact marginal distributions at every vertex of a graphical model without cycles. While BP is designed to work correctly on trees, it is routinely applied to general graphical models that may contain cycles, in which case neither convergence, nor correctness in the case of convergence is guaranteed. Nonetheless, BP gained ...
متن کاملSurvey Propagation: Iterative Solutions to Constraint Satisfaction Problems
Iterative algorithms, such as the well known Belief Propagation algorithm, have had much success in solving problems in statistical inference and coding and information theory. Survey Propagation attempts to apply iterative message passing algorithms to solve difficult combinatorial problems, in particular constraint satisfaction problems such as k-sat and coloring problems. Intuition from stat...
متن کاملOn local equilibrium equations for clustering states
In this note we show that local equilibrium equations (the generalization of the TAP equations or of the belief propagation equations) do have solutions in the colorable phase of the coloring problem. The same results extend to other optimization problems where the solutions has cost zero (e.g. K-satisfiability). On a random graph the solutions of the local equilibrium equations are associated ...
متن کاملDecomposition During Search for Propagation-Based Constraint Solvers
We describe decomposition during search (DDS), an integration of and/or tree search into propagation-based constraint solvers. The presented search algorithm dynamically decomposes sub-problems of a constraint satisfaction problem into independent partial problems, avoiding redundant work. The paper discusses how DDS interacts with key features that make propagation-based solvers successful: co...
متن کاملCounting-Based Look-Ahead Schemes for Constraint Satisfaction
The paper presents a new look-ahead scheme for backtracking search for solving constraint satisfaction problems. This look-ahead scheme computes a heuristic for value ordering and domain pruning. The heuristic is based on approximating the number of solutions extending each partial solution. In particular, we investigate a recent partitionbased approximation of tree-clustering algorithms, Itera...
