WebOct 7, 2024 · Tarjan’s Algorithm for Strongly Connected Components Vrishchik Strongly connected components (SCCs) can be thought of as self-contained cycles within a directed graph where every vertex in a given cycle can reach every other vertex in the same cycle. 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:
