A graph G \(=(V,E)\) is called a complete graph when \(xy\) is an edge in G for every distinct pair \(x,y \in V\). A complete graph with 14 vertices has 14(13) 2 14 ( 13) 2 edges. This is 91 edges. However, for every traversal through a vertex on a path requires an in-going and an out-going edge. Thus, with an odd degree for a vertex, the number of times you must visit a vertex is the degree of the vertex divided by 2 using ceiling division (round up).As the names indicate sparse graphs are sparsely connected (eg: Trees). Usually the number of edges is in O (n) where n is the number of vertices. Therefore adjacency lists are preferred since they require constant space for every edge. Dense graphs are densely connected.
