查询词典 transitive relation

In this paper, we deal with the complete extension of a fuzzy relation and obtain the following main conclusion. Every reflexive,*-antisymmetric and *-transitive fuzzy relation can be extended to a complete reflexive,*-antisymmetric and *-transitive fuzzy relation, namely, every partial order can be extended to a linear order.

In the paper, the kinds of reachability notions are defined and charactered firstly in their matrices and graphs. By the discussion of the matrix standard form and its transitive closure, the relation among the maximum partial reachability sets, the standard form of the matrix and its transitive closure are posted and the network partial reachability is based. The standard form provides methods for the improvement of the network reachability.

of transitive closure based on equivalence relation, method of maximum fuzzy spanning tree based on fuzzy graph, and algorithm Fuzzy C-Means based on partition are more deeply investigated.
