WebA loop is an edge that joins a vertex to itself. Graphs as defined in the two definitions above cannot have loops, because a loop joining a vertex to itself is the edge (for an undirected simple graph) or is incident on (for an … WebEdge Lists¶ Read and write NetworkX graphs as edge lists. The multi-line adjacency list format is useful for graphs with nodes that can be meaningfully represented as strings. With the edgelist format simple edge data can be stored but node or graph data is not. There is no way of representing isolated nodes unless the node has a self-loop edge. theory xbc2

An edge-list representation of a graph is simply a sequence of edges, where each edge is represented as a pair of vertex ID's. The memory required is only O(E). Edge insertion is typically O(1), though accessing a particular edge is O(E) (not efficient). Figure 5 shows an edge-list representation of the graph in Figure 1.
