WebJul 3, 2024 · A Strongly Connected Component is the smallest section of a graph in which you can reach, from one vertex, any other vertex that is also inside that section. In slightly more theoretical terms, an SCC is a strongly connected subgraph of some larger graph G. So that graph above has four SCCs. Every single node is its own SCC. WebThe Kosaraju algorithm is a DFS based algorithm used to find Strongly Connected Components (SCC) in a graph. It is based on the idea that if one is able to reach a vertex v starting from vertex u, then one should be able to reach vertex u starting from vertex v and if such is the case, one can say that vertices u and v are strongly connected ... office desk against wall
