WebThis classification of the non-tree edges can be used to derive several useful properties of the graph; for example, we will show in a moment that a graph is acyclic if and only if it … WebMar 27, 2024 · Tree Edge: It is a edge which is present in tree obtained after applying DFS on the graph. All the Green edges are tree edges. Forward Edge: It is an edge (u, v) such that v is descendant but not part of the DFS tree. Edge from 1 to 8 is a forward edge. Back edge: It is an edge (u, v) such that v is ancestor of edge u but not part of DFS tree.
WebTree Edge, if in edge (u,v), v is first discovered, then (u, v) is a tree edge. Back Edge, if ....., v is discovered already and v is an ancestor, then it's a back edge. Forward Edge, if ....., v is discovered already and v is a descendant of u, forward edge it is. Cross Edge, all edges except for the above three.
