What are weakly connected components?

Given a directed graph, a weakly connected component (WCC) is a subgraph of the original graph where all vertices are connected to each other by some path, ignoring the direction of edges. In case of an undirected graph, a weakly connected component is also a strongly connected component.

What are weak components?

A weak component is a maximal subgraph which would be connected if we ignored the direction of the arcs. A cutpoint is a vertex whose removal from the graph increases the number of components. That is, it makes some points unreachable from some others.

What do you mean by strongly connected components?

Definition A strongly connected component of a directed graph G is a maximal set of vertices C ⊆ V such that for every pair of vertices u and v, there is a directed path from u to v and a directed path from v to u.

What is strongly connected digraph?

A strongly connected digraph is a directed graph in which it is possible to reach any node starting from any other node by traversing edges in the direction(s) in which they point. The nodes in a strongly connected digraph therefore must all have indegree of at least 1.

What is your weakest health related fitness component?

Weight Training Exercise You can use all forms of resistance training to increase your muscular strength. If your strength is your weakest of the 5 components of physical fitness you need to start weight training.

What does weakly connected mean?

Weakly Connected: A graph is said to be weakly connected if there doesn’t exist any path between any two pairs of vertices. Hence, if a graph G doesn’t contain a directed path (from u to v or from v to u for every pair of vertices u, v) then it is weakly connected.

How do you find weakly connected components?

Algorithm to find Weakly Connected Component:

1. Construct the underlying undirected graph of the given directed graph.
2. Find all the connected components of the undirected graph.
3. The connected components of the undirected graph will be the weakly connected components of the directed graph.

Is strongly connected components a cycle?

A strongly connected component (SCC) of a directed graph G = (V,E) is a maximal set of vertices such that any two vertices in the set are mutually reachable. Intuitively, we think of a SCC as a cycle.
