Web‘ac’ and ‘cd’ are the adjacent edges, as there is a common vertex ‘c’ between them. Parallel Edges In a graph, if a pair of vertices is connected by more than one edge, then those edges are called parallel edges.

WebJul 26, 2024 · Thus we usually don't use matrix representation for sparse graphs. We prefer adjacency list. But if the graph is dense then the number of edges is close to (the complete) n ( n − 1) / 2, or to n 2 if the graph is directed with self-loops. Then there is no advantage of using adjacency list over matrix.
