Correlation-based decimation in constraint satisfaction problems

We study hard constraint satisfaction problems using some decimation algorithms based on mean-field approximations. The message-passing approach is used to estimate, beside the usual one-variable marginals, the pair correlation functions. The identification of strongly correlated pairs allows to use a new decimation procedure, where the relative orientation of a pair of variables is fixed. We a...

Decimation flows in constraint satisfaction problems

We study hard constraint satisfaction problems with a decimation approach based on message passing algorithms. Decimation induces a renormalization flow in the space of problems, and we exploit the fact that this flow transforms some of the constraints into linear constraints over GF(2). In particular, when the flow hits the subspace of linear problems, one can stop decimation and use Gaussian ...

Solving Constraint Satisfaction Problems through Belief Propagation-guided decimation

Message passing algorithms have proved surprisingly successful in solving hard constraint satisfaction problems on sparse random graphs. In such applications, variables are fixed sequentially to satisfy the constraints. Message passing is run after each step. Its outcome provides an heuristic to make choices at next step. This approach has been referred to as ‘decimation,’ with reference to ana...

Constraint Satisfaction Search 1 Constraint Satisfaction Problems

For the past thirty ve years artiicial intelligence researchers have been studying heuristic search techniques. People writing AI programs have had strong intuitions about what it means for a program to search. Intuitively they classiied programs according to the kinds of search performed. Certain programs, such as matrix multiplication routines, did no search whatsoever. Other programs searche...
