Constraint compiling into rules formalism constraint compiling into   rules formalism for dynamic CSPs computing
  In this paper we present a rule based formalism for filtering variables domains of constraints. This formalism is well adapted for solving dynamic CSP. We take diagnosis as an instance problem to illustrate the use of these rules. A diagnosis problem is seen like finding all the minimal sets of constraints to be relaxed in the constraint network that models the device to be diagnosed
