In approximate halfspace range counting, one is given a set P of n points in ℝd , and an e>0, and the goal is to preprocess P into a data structure which can answer efficiently queries of the form: Given a halfspace h, compute an estimate N such that (1−e)|P∩h|≤N≤(1+e)|P∩h|. Several recent papers have addressed this problem, including a study by Kaplan and Sharir (Proc. 17th Annu. ACM-SIAM Sympos. Discrete Algo., pp. 484–493, 2006), which is based, as is the present paper, on Cohen’s technique for approximate range counting (Cohen in J. Comput. Syst. Sci. 55:441–453, 1997). In this approach, one chooses a small number of random permutations of P, and then constructs, for each permutation π, a data structure that answers efficiently minimum range queries: Given a query halfspace h, find the minimum-rank element (according to π) in P∩h. By repeating this process for all chosen permutations, the approximate count can be obtained, with high probability, using a certain averaging process over the minimum-rank outputs. In the previous study, the authors have constructed such a data structure in ℝ3, using a combinatorial result about the overlay of minimization diagrams in a randomized incremental construction of lower envelopes. In the present work, we propose an alternative approach to the range-minimum problem, based on cuttings, which achieves better performance. Specifically, it uses, for each permutation, O(n ⌊d/2⌋(log log n)c /log ⌊d/2⌋ n) expected storage and preprocessing time, for some constant c, and answers a range-minimum query in O(log n) expected time. We also present a different approach, based on “antennas,” which is simple to implement, although the bounds on its expected storage, preprocessing, and query costs are worse by polylogarithmic factors.
