Slimming down search structures: A functional approach to algorithm design
Bernard Chazelle · 1985
We establish new upper bounds on the complexity of several "rectangle" problems. Our results include, for instance, optimal algorithms for range counting and rectangle searching in two dimensions. These involve linear space implementations of range trees and segment trees. The algorithms we give are simple and practical; they can be dynamized and taken into higher dimensions. Also of interest is the nonstandard approach which we follow to obtain these results: it involves transforming data structures on the basis of functional specifications.
