We study the complexity of the λ−L(p, q)-labelling problem for fixed λ, p, and q. The task is to assign vertices of a graph labels from the set {0, . . . , λ} such that labels of adjacent vertices differ by at least p while vertices with a common neighbor have different labels. We use two different reductions, one from the NAE-3SAT and the second one from the edge precoloring extension problem. 1
