edge_coloring (671B)


      1 # Edge coloring
      2 
      3 A function mapping the [edges] of an [undirected_graph] to colors such that no two incident edges get the same color
      4 
      5 An easy lower bound on the number of colors required is the [maximum_degree]
      6 
      7 [Vizings_theorem]: the number of colors needed is always at most the [maximum_degree] plus one
      8 
      9 It is [NP_hard] to determine which of the two applies
     10 
     11 Computing edge colorings whose number of colors is the [maximum_degree] plus one can now be done in [near_linear_time]
