Abstract
Lower bounds on the complexity of orthogonal range searching in the static case are established. Specifically, we consider the following dominance search problem: Given a collection of
n
weighted points in
d
-space and a query point
q
, compute the cumulative weight of the points dominated (in all coordinates) by
q
. It is assumed that the weights are chosen in a commutative semigroup and that the query time measures only the number of arithmetic operations needed to compute the answer. It is proved that if
m
units of storage are available, then the query time is at least proportional to (log
n
/log(2
m
/
n
))
d
–*1
in both the worst and average cases. This lower bound is provably tight for
m
= Ω(
n
(log
n
)
d
–1+ϵ)
and any fixed ϵ > 0. A lower bound of Ω(
n
/log log
n
)
d
) on the time required for executing
n
inserts and queries is also established.
