A directed graph is strongly connected if there is a path from a to b and from b to a whenever a and b are vertices in the graph Weakly Connected A directed |
How do you check whether a graph is connected or not?
A graph is said to be connected if every pair of vertices in the graph is connected.
This means that there is a path between every pair of vertices.
An undirected graph that is not connected is called disconnected.How to find Strongly Connected Components in a Graph?
How to find Strongly Connected Components in a Graph?
1Call DFS(G) to compute finishing times f[u] for each vertex u.
2) Compute Transpose(G)3Call DFS(Transpose(G)), but in the main loop of DFS, consider the vertices in order of decreasing f[u] (as computed in step 1)
How do you tell if a graph is strong or weak?
A directed graph is strongly connected if there is a path from a to b and from b to a whenever a and b are vertices in the graph.
A directed graph is weakly connected if there is a path between every two vertices in the underlying undirected graph.

Discrete Mathematics & Mathematical Reasoning Chapter 10: Graphs
Informally, a graph consists of a non-empty set of vertices (or nodes), and a set E of edges that connect (pairs of) nodes But different Each directed edge (u,v) ∈ E has a start (tail) vertex u, and a end (head) Example: Determine whether these two graphs is a maximal strongly connected subgraph H of G which is not |
