Labeling is crucial in the performance of solving timetabling problems with constraint programming. Traditionally , labeling strategies are based on static and dynamic information about variables and their domains, and selecting variables and values to assign. However, the size of combinatorial problems tractable by these techniques is limited. In this(More)
— This paper introduces some concepts of interval-valued fuzzy relations and some of their properties: reflexivity, symmetry , T-transitivity, composition and locally reflexivity. It is also introduced the concept of T-transitive closure for an interval-valued fuzzy relation. An algorithm to compute the T-transitive closure of finite interval-valued(More)
Functional trait diversity can provide insight into ecosystem function beyond that provided by species diversity measures. The relationship between functional diversity and natural stressors has received less attention compared to anthropogenic stressors. In this study, we investigated how two natural stressors, water salinity and flow intermittence, affect(More)
In this paper are introduced some concepts of interval-valued fuzzy relations and some of their properties: reflexivity, symmetry, T-transitivity, composition and local reflexivity. The existence and uniqueness of T-transitive closure of interval-valued fuzzy relations is proved. An algorithm to compute the T-transitive closure of finite interval-valued(More)
