They form a spanning tree of GG, rooted at the vertex 1. We'll call these edges span-edges; all other edges are called back-edges. This is the DFS tree of our graph: Observation 1. The back-edges of the graph all connect a vertex with its descendant in the spanning tree. This is...

Depth-first search (DFS) is an algorithm for traversing or searching tree or graph data structures. One starts at the root (selecting some arbitrary node as the root in the case of a graph) and explores as far as possible along each branch before backtracking. ...
