WebbChapter 1 Introduction The range searching problem involves preprocessing a set P of n points in Rd so that given a region R, a predefined function f(P ∩ R) can be computed efficiently. The region R is called a range, and it is drawn from a predefined range space … WebbThe approach which we take is very general and rests on a new concept called filtering search. We show on a number of examples how it can be used to improve the complexity of known algorithms and simplify their implementations as well.
