Abstract

Lower bounds on the complexity of orthogonal range searching in thestatic case are established. Specifically, we consider the followingdominance search problem: Given a collection ofn weighted points ind-space and a query pointq, compute the cumulative weight ofthe points dominated (in all coordinates) byq. It is assumed that the weights arechosen in a commutative semigroup and that the query time measures onlythe number of arithmetic operations needed to compute the answer. It isproved that if m units of storage areavailable, then the query time is at least proportional to (logn/log(2m/n))d–1in both the worst and average cases. This lower bound is provably tightfor m =&OHgr;(n(logn)d–1+&egr;) and any fixed &egr; 0. A lower bound of &OHgr;(n/loglogn)d)on the time required for executing ninserts and queries is also established. —Author's Abstract
