Given a graph G, the graph Gl has the same vertex setand two vertices are adjacent in Gl if and only if theyare at distance at most l in G. The l-coloring problem consists infinding an optimal vertex coloring of the graph Gl,where G is the input graph. We show that, for any fixed value of l,the l-coloring problem is polynomial when restricted to graphs ofbounded NLC-width (or clique-width), if an expression of the graphis also part of the input. We also prove that the NLC-width ofGl is at most 2(l+1)nlcw(G).
