The problem considered in this paper consists in defining an assignment of frequencies to radio links between transmitters/receivers which minimize the global interference inside the network. This problem can be modeled as a Constraint Satisfaction Problem CSP. It is NP-hard and several results have been reported on techniques for solving it optimally. We applied to this version of the frequency assignment...
In order to increase the effectiveness and the adaptability of methods, the constraints programming has gradually evolved to hybrid algorithms which combine exact and approximated methods in order to get the advantages of each of them. In this paper we propose a deterministic hybrid method which combines the backtracking, the constraints propagation and the Tabu Search. The method is based on finding...
