Web1 nov. 2024 · Definition 5.8.2: Independent. A set S of vertices in a graph is independent if no two vertices of S are adjacent. If a graph is properly colored, the vertices that are assigned a particular color form an independent set. Given a graph G it is easy to find a proper coloring: give every vertex a different color.
