directed graph in data structure
What is a topological ordering of a directed graph?
A topological ordering of a directed graph is an ordering of its vertices into a sequence, such that for every edge the start vertex of the edge occurs earlier in the sequence than the ending vertex of the edge.
What is a directed graph?
Digraphs. A directed graph (or digraph ) is a set of vertices and a collection of directed edges that each connects an ordered pair of vertices. We say that a directed edge points from the first vertex in the pair and points to the second vertex in the pair. We use the names 0 through V-1 for the vertices in a V-vertex graph. Glossary.
What are the basic operations provided by a graph data structure?
The basic operations provided by a graph data structure G usually include: adjacent (G, x, y): tests whether there is an edge from the vertex x to the vertex y; neighbors (G, x): lists all vertices y such that there is an edge from the vertex x to the vertex y;
