We do DFS traversal of given graph with additional code to find out Articulation Points (APs). In DFS traversal, we maintain a parent[] array where parent[u] stores parent of vertex u. Among the above mentioned two cases, the first case is simple to detect. For every vertex, count chil...

We show that the articulation points can be found in O(m + n) time using O(n) space and one sequential pass of the graph. The previous best algorithm in the semi-streaming model also uses O(n) space and one pass, but has running time O(m伪(n) + n log n), where 伪 denotes ...

Abstract Given a directed graph G, an edge is a strong bridge if its removal increases the number of strongly connected components of G. Similarly, a vertex is a strong articulation point if its removal increases the number of strongly connected components of G. Strong articulation points and ...

For articulation points if we remove UU from the graph it will increase the number of connected components, but in the case of bridges if we remove the edge UVUV the number of connected components will remain the same. For bridges we need to be sure that the edge UVUV is not involved ...
