    • In computer science the notion of highly connected subgraphs appears frequently. This notion can be formalized as follows. Let [math]\displaystyle{ G=(E,V) }[/math] be an undirected graph and let [math]\displaystyle{ S=(E_S,V_S) }[/math] be a subgraph of [math]\displaystyle{ G }[/math] . Then the density of [math]\displaystyle{ S }[/math] is defined to be [math]\displaystyle{ d_S = {|E_S|\over|V_S|} }[/math] .

      The densest subgraph problem is that of finding a subgraph of maximum density. In 1984, Andrew V. Goldberg developed a polynomial time algorithm to find the maximum density subgraph using a max flow technique.
