Web2. DF and BF Search Def 2.1. The output trees produced by the depth- rst and breadth- rst searches of a graph are called the depth- rst tree (or dfs-tree) and the breadth- rst tree (or bfs-tree). As previewed in x4.1, depth- rst search and breadth- rst search use two opposite priority rules for the function nextEdge.
