However, there is always some order of the edges for which the greedy algorithm uses exactly the minimum number of colors required. Our aim in this paper is to construct an order of the edges such that the greedy algorithm uses at most 22 colors. Through- bixby the beaver

So the algorithm is correct, but will not always give the optimal coloring (i.e. least number of colours used). A more common ordering is to order the vertices by their degree, known as the Welsh–Powell algorithm.
