Given a set V of points in the plane, a sequence d 0 ; d 1 ; : : : ; d k of non-negative numbers and an integer n, we are interested in the problem to assign integers from f0; : : : ; n?1g to the points in V such that if x;y 2 V are two points with euclidean distance less than d i , then the diierence between the labels of x and y is not equal to i.
