WebAug 9, 2024 at 18:23. @ElleryL, I'm pretty sure this is true for an undirected graph. In an undirected graph, BFS should only produce tree edges and cross edges. Cross edges will always be produced if there are cycles in the undirected graph (i.e. m ≥ n ). This is similar to how dfs on undirected graph produces only tree edges and back edges.
