WebIn graph theory, Vizing's theorem states that every simple undirected graph may be edge colored using a number of colors that is at most one larger than the maximum degree Δ of the graph. At least Δ colors are always necessary, so the undirected graphs may be partitioned into two classes: "class one" graphs for which Δ colors suffice, and "class … WebOct 12, 2024 · I have seen some papers which tackle how to approximate a coloring for a graph known to be $3$-colored, yet hardly found any approximations for a general …
