English: Optimal coloring of a split graph, a graph that can be partitioned into a maximal clique (heavy vertices and edges) and an independent set (light vertices). The coloring is obtained by giving a separate color to each vertex in the clique, and then giving each vertex in the independent set the same color as a clique vertex that it is not adjacent to.
