WebNov 20, 2024 · A DFS-Forest Component is any set of nodes within the DFS-Forest that are strongly connected (a path between all pairs of vertices in the component exists). In an undirected graph, I'd imagine this means that every node is a part of the same component, but in a directed graph this isn't necessarily the case. Share.
