在图论中,拓扑排序(Topological Sorting)是一个有向无环图(DAG, Directed Acyclic Graph)的所有顶点的线性序列。且该序列必须满足下面两个条件: 每个顶点出现且只出现一次。 若存在一条从顶点 A 到顶点 B 的路径,那么在序列中顶点 A 出现在顶点 B 的前面。
Topological Sorting拓扑排序 定义: Topological Sorting is a method of arranging the vertices in a directed acyclic graph (DAG有向无环图) as a sequence, such that for every directed edge(u,v), 即u-> v, vertex u comes before v in the ordering...
