WebIn graph theory, Brooks' theorem states a relationship between the maximum degree of a graph and its chromatic number.According to the theorem, in a connected graph in which every vertex has at most Δ neighbors, the vertices can be colored with only Δ colors, except for two cases, complete graphs and cycle graphs of odd length, which require Δ + 1 colors.
