While trying to studying graph theory and implementing some algorithms, I was regularly getting stuck, just because it was so boring. The best way to understand something is to understand its applications. WebJan 1, 2016 · The applications of graph theory are numerous in science and engineering. A few are listed below. Graph Theory in Spatial Networks. The very fact that graph theory was born when Euler solved a problem based on the bridge network of the city of Konigsberg points to the apparent connection between spatial networks (e.g. …

In graph theory, a bridge, isthmus, cut-edge, or cut arc is an edge of a graph whose deletion increases the graph's number of connected components. Equivalently, an edge is a bridge if and only if it is not contained in any cycle. For a connected graph, a bridge can uniquely determine a cut. A graph … See more A graph with $${\displaystyle n}$$ nodes can contain at most $${\displaystyle n-1}$$ bridges, since adding additional edges must create a cycle. The graphs with exactly $${\displaystyle n-1}$$ bridges are exactly the See more A very simple bridge-finding algorithm uses chain decompositions. Chain decompositions do not only allow to compute all bridges of a graph, they also allow to read off every See more Bridges are closely related to the concept of articulation vertices, vertices that belong to every path between some pair of other vertices. The two endpoints of a bridge are articulation vertices … See more A bridgeless graph is a graph that does not have any bridges. Equivalent conditions are that each connected component of … See more • Biconnected component • Cut (graph theory) See more WebJun 8, 2024 · Finding bridges in a graph in O ( N + M) We are given an undirected graph. A bridge is defined as an edge which, when removed, makes the graph disconnected (or more precisely, increases the number of connected components in the graph). The task is to find all bridges in the given graph.
