Graph undirected
WebThis means that if we can solve the 4-colorable problem efficiently, we can also solve the 3-colorable problem efficiently. Let G = (V, E) be an undirected graph that we want to determine if it is 3-colorable. We will construct a new graph G' = (V', E') as follows: For each edge (u, v) in G, add a new node x to G' and connect it to u and v: V ... WebNov 13, 2012 · For example, in Facebook, each person is represented with a vertex (or node). Each node is a structure and contains information like person id, name, gender, and locale.
