  • What is a strongly connected graph give an example?

    Definitions. A directed graph is called strongly connected if there is a path in each direction between each pair of vertices of the graph. That is, a path exists from the first vertex in the pair to the second, and another path exists from the second vertex to the first.

  • What is an example for strongly connected components?

    For example: Pop vertex-0 from the stack. Starting from vertex-0, traverse through its child vertices (vertex-0, vertex-1, vertex-2, vertex-3 in sequence) and mark them as visited. The child of vertex-3 is already visited, so these visited vertices form one strongly connected component.

  • How do you check if a graph is strongly connected or not?

    If there is a path connecting each pair of the graph's vertices in each direction, a directed graph is said to be strongly connected. The first vertex in the pair has a path leading to the second, and the second vertex has a path leading to the first.
  • Definition: A directed graph that has a path from each vertex to every other vertex. Formal Definition: A directed graph D=(V, E) such that for all pairs of vertices u, v ? V, there is a path from u to v and from v to u.
