Construction of simple path graphs in transport networks: II. Analysis of graphs' biconnectivity
The problem of constructing all simple paths in an undirected graph that pairwise connect vertices from the given set is interpreted as constructing a graph that is a union of these paths. This construction relies on the computation of biconnected components and bridges of the source graph. A new al...

| Zusammenfassung: | The problem of constructing all simple paths in an undirected graph that pairwise connect vertices from the given set is interpreted as constructing a graph that is a union of these paths. This construction relies on the computation of biconnected components and bridges of the source graph. A new algorithm which makes this computation more transparent and controllable is proposed. Its idea is to track opening and closing of chords at the depth-first search. Due to the clarity of the proposed solution, its correctness is obvious without much justification. This is its advantage over the well-known Hopcroft-Tarjan algorithm. The proposed algorithm makes self-evident the obtaining biconnected components of a graph by successive uniting its fundamental cycles that have common edges. |
