What is a strongly connected directed graph?
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.
How do you find the strongly connected directed graph?
Three steps are involved.
1Perform a depth first search on the whole graph. 2Reverse the original graph. 3Perform depth-first search on the reversed graph. 4Thus, the strongly connected components are: All strongly connected components.
What is a DAG of its strongly connected components?
Property Every directed graph is a dag of its strongly connected components. This tells us something important: The connectivity structure of a directed graph is two-tiered. At the top level we have a dag, which is a rather simple structure—for instance, it can be linearized.
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.
