Kosaraju algorithm

Description of the algorithm Described algorithm was independently suggested by Kosaraju and Sharir at 1979. This is an easy-to-implement algorithm based on two series of depth first search, and working for O (n + m) time.

It makes use of the fact that the The primary topics in this part of the specialization are: data structures (heaps, balanced search trees, hash tables, bloom filters), graph primitives (applications of breadth-first and depth-first search, connectivity, shortest paths), and their applications (ranging from deduplication to social network analysis). Kosaraju's Linear time algorithm to find Strongly Connected Components: This algorithm just does  Kosaraju's Algorithm-Strongly connected components In Kosaraju's Algorithm, using first dfs (traversing on reverse graph) we calculate finishing time of nodes,  Order of steps in Kosaraju's algorithm [closed] · Pop the top vertex v from S. · Perform a depth-first search starting at v in the transpose graph. · The set of visited  Kosaraju's algorithm uses 2 depth first searches to find the strongly connected components of a graph in linear time.

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.
