Given a graph H, the Ramsey number r (H) is the smallest natural number N such that any two-colouring of the edges of K N contains a monochromatic copy of H.The existence of these numbers has been known since 1930 but their quantitative behaviour is still not well understood. Even so, there has been a great deal of recent progress on the …

Generally, it is said that a graph with n vertices is dense if it has Theta ( n ^2) edges and is sparse otherwise. This means that a graph is dense if the average degree of each vertex is lineal, and sparse if sublineal. Sparsity does not deppend on size.

Web26 de set. de 2012 · 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. Here number of edges is usually O (n^2).
