Depth first search is a very useful technique for analyzing graphs For example it can be used to: • Determine the connected components of a graph
How do you find the connected components of a directed graph?
We start by initializing all the vertices to the flag not visited. We then choose any random vertex to start and check if we've visited the vertex or not. If we didn't, we call the DFS function. Once all the vertices marked as visited, the algorithm terminates and prints the number of the connected components.How to find strongly connected components in a directed graph?
Suppose the graph has adjacency matrix A and n vertices. Compute M=(A+I)n. Now define vertices u and v to be equivalent if Mu,v?0. The equivalence classes of this relation are the connected components of the graph.
