We show that a graph has tree-width at most 4k–1 if its line graph has nLC-width or clique-width at most k, and that an incidence graph has tree-width at most k if its line graph has nLC-width or clique-width at most k. In [9] it is shown that a line graph has nLC-width at most k+2 and clique-width at most 2k+2 if the root graph has tree-width k. Using these bounds we show by a reduction from tree-width minimization that nLC-width minimization is nP-complete.
