Edge density of a graph

WebIn this paper, in order to describe complex network systems, we firstly propose a general modeling framework by combining a dynamic graph with hybrid automata and thus name it Dynamic Graph Hybrid Automata (DGHA). Then we apply this framework to model traffic flow over an urban freeway network by embedding the Cell Transmission Model (CTM) … In mathematics, a dense graph is a graph in which the number of edges is close to the maximal number of edges (where every pair of vertices is connected by one edge). The opposite, a graph with only a few edges, is a sparse graph. The distinction of what constitutes a dense or sparse graph is ill-defined, and depends on context. The graph density of simple graphs is defined to be the ratio of the number of edges E with res…

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. In terms of space complexity.
