A simpler answer without binomials: A complete graph means that every vertex is connected with every other vertex. If you take one vertex of your graph, you therefore have n − 1 n − 1 outgoing edges from that particular vertex. Now, you have n n vertices in total, so you might be tempted to say that there are n(n − 1) n ( n − 1) edges ...Fully connected graph: Another approach is to start with a fully connected graph and assign edge weights using the available meta-data or employ the GNN variants that provide weights for each edge via an attention mechanism [50, 59].

Let (V;E) be a connected graph and de ne the graph distance as You could pass a pointer to an array containing all the nodes. You could pass just the one starting node and work from there, if it's a fully connected graph. And finally, you could write a graph class with whatever data structures you need inside it, and pass a reference to an instance of that class.Definitions. A clique, C, in an undirected graph G = (V, E) is a subset of the vertices, C ⊆ V, such that every two distinct vertices are adjacent.This is equivalent to the condition that the induced subgraph of G induced by C is a complete graph.In some cases, the term clique may also refer to the subgraph directly.
