Abstract

We present in this paper fast algorithms for the 3-D dominance reportingand counting problems, and generalize the results to the d-dimensional
case. Our 3-D dominance reporting algorithm achieves $O(\log n/\log\log n
+f)$ query time using $O(n\log^{\epsilon}n)$ space, where $f$ is the
number of points satisfying the query and $\epsilon>0$ is an arbitrary
small constant. For the 3-D dominance counting problem (which is
equivalent to the 3-D range counting problem), our algorithm runs in
$O((\log n/\log\log n)^2)$ time using $O(nlog^{1+\epsilon}n/\log\log n)$
space.
