Abstract : Constraint propagation is at the heart of constraint solvers. Two main trends co-exist: variable-oriented propagation engines and constraint-oriented propagation engines. Those two approaches ensure the same consistency level, generally arc-consistency, but their efficiency (computation time) can be quite different depending on the instance solved. It is usually accepted that there is no best approach in general, and modern constraint solvers implement only one. In this paper, we would like to go a step further providing a solver independent language at the modeling stage to enable the design of propagation engine prototypes. We validate our proposal with a reference implementation based on Choco and the MiniZinc modeling language.
