Transforming ordered constraint hierarchies into ordinary constraint systems,uately. We substantiate our proposition by an example. Then we present a new method to transform constraint hierarchies into equivalent ordinary constraint systems. For practical applications, we present a modified algorithm based on an incomplete finite domain constraint solver. We conclude with a

RODE

A compositional theory of constraint hierarchies (Operational semantics),ncrementality in Constraint Logic Programming, introduce HCLP, and present Wilson‘s proof that it is non-compositional. We define a scheme which uses bags (multisets) called BCH (Bags for the Composition of Hierarchies) for composing together solutions to individual hierarchies; it calculates a supe

極力證明

Cascaded directed arc consistency and no-good learning for the maximal constraint satisfaction prob, used in conjunction with forward checking. After computing directed arc consistency counts, inferred counts are derived for each value, based on the counts of supporting values in future variables. This inference process can be ‘cascaded’ from the end to the beginning of the search order, to augme

Gustatory

Partial arc consistency,tency in a constraint network is a commonly used preprocessing step before identifying the globally consistent value assignments to all the variables. Since many constraint networks that arise in practice are overconstrained, any global assignment of values to the variables involved, is expected to

平靜生活

Dynamic constraint satisfaction with conflict management in design,in an intelligent CAD system using a dynamic constraint satisfaction framework and a conflict resolution paradigm. Navigation between different design spaces is controlled by assumptions the designer makes in situations of incomplete knowledge. These assumptions divide design constraints into defaul

Ablation

Implementing constraint relaxation over finite domains using assumption-based truth maintenance sys a constraint relaxation mechanism fully integrated with the constraint solver. Such a constraint relaxation system must be able to perform two fundamental tasks: identification of constraints to relax and efficient constraint suppression. Assumption-based Truth Maintenance Systems propose a uniform
