Good luck in understanding, these guys are crazy. A generator of sets of nodes, one for each component of G. Generate a sorted list of connected components, largest first. Loop through all vertices which are still unlabeled and call BFS on those unlabeled vertices to find other components. Let us take the graph below. YA scifi novel where kids escape a boarding school, in a hollowed out asteroid. It means that component ids are generally not contiguous. Thanks. @user3211198 BFS and DFS are same from performance perspective. @ThunderWiring I do not agree with your statement "that if some node Y is not reachable from X, then BFS won't visit it. Both complete on O(n) time, using O(n) memory, where n is matrix size. O(V+E). Sometimes called connected components, some graphs have very distinct pieces that have no paths between each other, these 'pi. Recall that we use the convention where 'component_id' is the id of the first vertex in a particular group. Every vertex of the graph lies in a connected component that consists of all the vertices that can be reached from that vertex, together with all the edges that join those vertices. But I suggest you BFS as far as it doesn't suffer from stack overflow problem, and it doesn't spend time on recursive calls. Experts are tested by Chegg as specialists in their subject area. I have a random graph represented by an adjacency matrix in Java, how can I find the connected components (sub-graphs) within this graph? A graph is connected if and only if it has exactly one connected component.
