Abstract
The online nearestneighbour graph on a sequence of n uniform random points in (0,1)d joins each point after the first to its nearest neighbour amongst its predecessors. For the total powerweighted edgelength of this graph, with weight exponent αset membership, variant(0,d/2], we prove O(max{n1−(2α/d),logn}) upper bounds on the variance. On the other hand, we give an n→∞ largesample convergence result for the total powerweighted edgelength when α>d/2. We prove corresponding results when the underlying point set is a Poisson process of intensity n.
