“…Ce compilateur permet de compiler d'une part des VCSPsà valuations additives [5] dont les contraintes sont exprimées par des tables tuple →valuation (selon le format XCSP 2.1 dé-crit dans [16]) sous la forme de SLDD + ; et d'autre part de compiler des réseaux bayésiens sous la forme de SLDD × (selon le format XML de [7]). Pour permettre l'obtention de différents types de VDDs, nous avonś egalement implémenté des traductions de SLDD + et SLDD × vers ADD et réciproquement, ainsi que des traductions de SLDD + et SLDD × vers AADD.…”

“…While much effort has been devoted to the representation issue for utility functions or preorders (complete or partial) for the last years (see among others [9,[1][2][3]12,17,4]), the compact representation of interval orders has not been addressed so far (as far as we know).…”

“…Several alternative mathematical frameworks for soft constraints have been proposed in the literature, including the very general frameworks of 'semi-ring based constraints' and 'valued constraints' [1]. For simplicity, we shall adopt the valued constraint framework here (although our results can easily be adapted to the semi-ring framework, for appropriate semi-ring structures).…”

“…A number of authors have suggested that the usefulness of the constraint satisfaction framework could be greatly enhanced by extending the definition of a constraint to include also soft constraints, which allow different measures of desirability to be associated with different combinations of values [1]. In this extended framework a constraint can be seen as a function, mapping each possible combination of values to a measure of desirability or undesirability.…”
