The relative neighborhood graph (RNG) of a set S ofn points in R is a graph (S, E),where (p, q) &egr;E if and only if there is no pointz &egr;S such that max{d(p, z), d(q,z)} d(p,q). We show that inR,RNG(S) hasO(n4/3)edges. We present a randomized algorithm that constructsRNG(S) in expected timeO(n3/2+&egr;)assuming that the points of S are ingeneral position. If the points of Sare arbitrary, the expected running time isO(n7/4+&egr;).These algorithms can be made deterministic without affecting theirasymptotic running time.
