Abstract

We present linear-space sublogarithmic algorithms for handling the {\emthree-dimensional dominance reporting problem} and the {\em
two-dimensional range counting problem}. Under the RAM model as described
in~[M.~L. Fredman and D.~E. Willard. ``Surpassing the information
theoretic bound with fusion trees'', {\em Journal of Computer and System
Sciences}, 47:424--436, 1993], our algorithms achieve $O(\log n/\log\log
n+f)$ query time for 3-D dominance reporting, where $f$ is the number of
points reported, and $O(\log n/\log\log n)$ query time for 2-D range
counting case. We extend these results to any constant dimension $d$
achieving $O(n(\log n/\log\log n)^{d-3})$-space and $O((\log n/\log\log
)^{d-2}+f)$-query time for the reporting case and $O(n(\log n/\log\log
n)^{d-2})$-space and $O((\log n/\log\log n)^{d-1})$ query time for the
counting case.
