(definition)
Definition: A graph in which the number of edges is close to the possible number of edges.
Generalization (I am a kind of ...)
graph.
Specialization (... is a kind of me.)
complete graph.
See also sparse graph, adjacency-matrix representation.
Note: A directed graph can have at most n(n-1) edges, where n is the number of vertices. An undirected graph can have at most n(n-1)/2 edges.
There is no strict distinction between sparse and dense graphs. Typically, a sparse (connected) graph has about as many edges as vertices, and a dense graph has nearly the maximum number of edges.
