AbstractWe present an improved space/query-time tradeoff for the general simplex range searching problem, matching known lower bounds up to small polylogarithmic factors. In particular, we construct a linear-space simplex range searching data structure withO(n1−1/d) query time, which is optimal ford=2 and probably also ford>2. Further, we show that multilevel range searching data structures can be built with only a polylogarithmic overhead in space and query time per level (the previous…

This work shows that the main techniques for simplex range searching in the plane can be adapted to the problem of computing the number of points in a query unit disk (i.e., all query disks have the same radius), and builds a data structure of $O(n)$ space so that each query can be answered in O(\sqrt{n}) time.

It is shown how idempotence can be used to improve not only approximate, but also exact halfspace range searching, because its data structures are much simpler than both their exact and relative model counterparts, and so are amenable to efficient implementation.

This work considers variations of range searching in which, given a query range, the goal is to compute some function based on frequencies of points that lie in the range to exhibit the hardness of these problems by reducing Boolean matrix multiplication to the construction and use of a range mode or least frequent element data structure.
