# taking the roots of the DFS trees in an order provided by the first DFS for G Θ(n +m) – adjacency lists Θ(n2) – adjacency matrix Name: Kosaraju's algorithm; 12.

In 1978, he wrote a paper describing a method to efficiently compute strongly connected members of a directed graph, a method later called Kosaraju's algorithm. Along with Paul Callahan he published many articles on efficient algorithms for computing the well-separated pair decomposition of a point set.

Perform a depth first search on the whole graph. Let us start from vertex-0, visit all of its child vertices, and mark the visited vertices as done. With the Kosaraju algorithm, you only need to do a strong communication component in the positive and reverse map. Faced with a dense map, the bottleneck of the Kosaraju algorithm is looking for points connected to point X and has not accessed.

### Kosaraju's Algorithm is based on the depth-first search algorithm implemented twice. Three steps are involved. Perform a depth first search on the whole graph. Let us start from vertex-0, visit all of its child vertices, and mark the visited vertices as done.

All edges are undirected. I have the following code that uses kosaraju 2DFS approach. import java.util.ArrayList; import java.util.Arrays; import java.util.HashMap; public class AirlineProblem { private static boolean The idea of Kosaraju’s algorithm is like this: 1. Compute the finishing time of all the vertices by doing a DFS on the reversed graph; 2. Replace the vertex index with its finishing time to get a new graph, DFS the new graph to compute each vertex’s leader vertex( in a strongly connected component(SCC) if … Finding Strongly Connected Components with DFS The Sharir-Kosaraju Algorithm Kosaraju algorithm is mainly phrased as two recursive subroutines running postorder DFS twice to mark SCCs with linear time complexity O(V+E) below, For each vertex u of the graph, mark u as unvisited. Let L be empty.

The first DFS of the graph identifies a “magic order” of the each node, and the second DFS of the graph is done using this “magic order”.

Following is detailed Kosaraju’s algorithm.

### Kosaraju’s algorithm is a two-pass algorithm. In the first pass, a Depth First Search (DFS) algorithm is run on the inverse graph to computing finishing time; the second pass uses DFS again to find out all the SCCs where the start note of each SCC follows the finishing time obtained in the first pass.
