Main topics:
To model  real problems,  constraint-based reasoning approaches  use a collection  of  local  constraints  to  capture the  properties  of  a solution.   However, most  (if  not  all) problems  in  life mix  hard requirements and preferences. Instead  of modeling preferences as hard requirements, which often  lead to over-constrained problems, specific approaches to deal with preferences are required.

This special issue of  the Constraints journal aims at collecting high  quality and original papers  dealing with preferences in constraint-based  reasoning, including  more generally any  kind of graphical models  generalizing constraint networks. The  issue is open to all aspects of preferences handling in constraint-based approaches, including:
The Constraints journal is a well-known journal published by Springer, with  ISI impact  factor 0.969  in 2007,  whose interests  include all aspects of constraint programming.
