Simplex Range Searching Revisited: How to Shave Logs in Multi-Level ...

WebbWe establish two new lower bounds for the halfspace range searching problem: Given a set of n points in R d , where each point is associated with a weight from a commutative semigroup, compute the semigroup sum of the weights of the points lying within any query halfspace. Letting m denote the space requirements, we prove a lower bound for gen- … WebbMainly we consider geometric range searching prob- lems, whose prototype is the following simplex range searching problem: Preprocess a set P of n points in Ed so that, given any query simplex u, the points in P n u can be counted or reported efficiently. WebbBesides deriving quasi-optimal solutions to simplex range searching in the arithmetic model, we also look at circular and polygonal range searching on a random access machine. Given n points in E2 we derive a data structure of size log n) for counting how many points fall inside a query convex k-gon (for arbitrary values of k). how is a battery chemical energy
