摘要
In this paper we present a linear space dynamic data structure for two-dimensional orthogonal range reporting and emptiness queries. This data structure answers range reporting queries in time O(log n log log n + k log(epsilon) 2n/k+1) for any epsilon > 0 and k the size of the answer. Our data structure also supports emptiness and one-reporting queries in time O(log n log log n). The model of computation used in this paper is a unit-cost RAM model.
