Web2 Answers. Connected is usually associated with undirected graphs (two way edges): there is a path between every two nodes. Strongly connected is usually associated with directed graphs (one way edges): there is a route between every two nodes. Complete graphs are undirected graphs where there is an edge between every pair of nodes. WebTarjan's strongly connected components algorithm is an algorithm in graph theory for finding the strongly connected components (SCCs) of a directed graph.It runs in linear time, matching the time bound for alternative methods including Kosaraju's algorithm and the path-based strong component algorithm.The algorithm is named for its inventor, … WebGraph (discrete mathematics) A graph with six vertices and seven edges.
