Given a graph G = (V,E) and a weight function w: E → R, a coloring of vertices of G, induced by w, is defined by χw(v) = e3v w(e) for all v ∈ V. In this paper, we show that determining whether a particular graph has a weighting of the edges from {1, 2} that induces a proper vertex coloring is NP-complete.
