WebSep 11, 2024 · Using Tarjan's algorithm, one can efficiently compute the transitive closure of a graph. (Given a graph G, the transitive closure of G is a graph that contains the same vertices and contains an edge from v to w if and only if there is a path from v to w in G .) The transitive closure is implemented in tarjan.tc: WebTarjan's algorithm for finding strongly connected components. *d [i] = Discovery time of node i. (Initialize to -1) *low [i] = Lowest discovery time reachable from node i. (Doesn't need to be initialized) *scc [i] = Strongly connected component of node i.
