摘要: Networks of constraints are a simple knowledge representation model, useful for describing large classes problems in picture recognition and scene analysis, the physical systems specification software systems. Nodes network represent variables to be assigned, while arcs satisfied by adjacent variables; simply seen as relation specifying acceptable tuples values variables. Solutions variable assignments which simultaneously satisfy all constraints.
