"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.
