Check if graph is strongly connected

WebNov 2, 2013 · How about this: 1 Begin at any arbitrary node of the graph, G 2.Proceed from that node using either depth-first or breadth-first search, counting all nodes reached. 3. Once the graph has been entirely traversed, if the number of nodes counted is equal to the number of nodes of G, the graph is connected; otherwise it is disconnected. – winston … WebJun 2, 2013 · A directed graph is strongly connected if there is a path between any two pair of vertices.
