Adjacency list for directed graph. Just like other data structures, we can represent graphs using two sequential representations: the Adjacency List and the Adjacency Matrix. If any back edge is found, the graph contains a cycle and cannot be topologically sorted. Directed graphs behave the same way, and adjacency lists are the most compact way to represent that outgoing flow. The adjacency matrix of the given graph (which has four nodes). DFS naturally detects cycles through back edges—edges that lead to vertices currently being processed (gray vertices). Let Γ n, for n ≥ 2, be the graph defined in the following way. Edge list: List of all node pairs representing the edges (plus list of nodes).
