Visually Explained Algorithms The edge list is another way to represent adjacent vertices. Why would you want to create an edge list? Again, to save time. The edge list is much more efficient when trying to figure out the adjacent nodes in a graph. Let’s look at an example of how someone would create an edge list from a directed graph. The edge list contains a list of edges in alphanumerical order. We start by filling in all the outbound edges from vertex 1. Vertex 1 has one outbound edge to vertex 6, so that edge is stored.
