Recent years have seen a significant increase in our understanding of high-dimensional nearest neighbor search (NNS) for distances like the lscr1 and lscr2 norms. By contrast, our understanding of the lscrinfin norm is now where it was (exactly) 10 years ago. In FOCSpsila98, Indyk proved the following unorthodox result: there is a data structure (in fact, a decision tree) of size O(nrho), for any...
We establish new lower bounds on the complexity of several searching problems. We show that the time for solving the partial sum problem on n points in d dimensions is at least proportional to (log n/log 2m/n)d-1 in both the worst and average cases; m denotes the amount of storage used. This bound is provably tight for m = Ω(nlogcn) and any c ≫ d- 1. We also prove a lower bound of Ω(n(log n/log log...
