Finding articulation points
WebJan 1, 2015 · Given an n-node m-edge graph G, the articulation points of graph G can be found in \(\mathcal {O}(m+n)\) time in the RAM model, through a DFS-based algorithm. In the semi-streaming model for large graphs, where memory is limited to \(\mathcal {O}(n \mathop {\mathrm {polylog}}n)\) and edges may only be accessed in one or more … WebArticulation Points represent single points of failure in a network. This fact is used to build reliable networks such that the networks don't contain a single point of failure. We can …
