Consider the chromatic index problem for K2m+1, the complete graphs with 2m + 1 vertices, m =1,2,.... The chromatic index of these graphs is known to be 2m + 1, the degree of the graphs plus one. Plantholt proved that K2m+1 - m, the graph obtained after removing arbitrary m edges from K2m+1, has the chromatic index 2m. In this paper, we present a much simpler constructive proof for this problem as well as an O(m(2)) optimal time algorithm for actually assigning colors to the edges. (C) 1998 Elsevier Science B.V.
