Graph biconnectivity
WebJan 23, 2024 · In this paper, we take a fundamentally different perspective to study the expressive power of GNNs beyond the WL test. Specifically, we introduce a novel class of expressivity metrics via graph biconnectivity and highlight their importance in both theory and practice. As biconnectivity can be easily calculated using simple algorithms that … WebTitle: Graph Biconnectivity Date Assigned: April 26, 2014 Date Due: May 12, 2014, 11:59pm Contact: James Edwards – [email protected] ... Biconnectivity is a property of undirected graphs; an undirected graph G is called biconnected if and only if it is connected and remains so after removing any vertex and all edges incident on that vertex.

WebThe Biconnectivity Problem: Input: a connected graph G Problem: Determine whether or not the graph is biconncted. If not biconnected, find all the articulation points. DFS on a connected graph G yields a DFS tree whose edges are from the graph. Draw those edges as straight edges. Add the remaining edges of the graph as dashed edges in the tree.

WebApr 28, 2024 · We consider undirected graphs without loops and multiple edges. The proper articulation point of such a graph is the vertex whose removal increases the quantity of connected components of the graph. The maximal connected subgraph of an undirected graph without its own articulation points is called a graph’s block [13, 14].Footnote 1 If a …
