Stats

Given a set P of n points in the plane and an integer 1 ≤ k ≤ n^2, the distance selection problem aims to find the k-th smallest interpoint distance among all pairs of points of P.
The algorithm improves upon previous deterministic solutions by reducing the time complexity to O(n^(4/3) log n).
For two-sided discrete Fréchet distance with shortcuts problem, the runtime is enhanced to O((m^(2/3)n^(2/3) * 2^O(log*(m+n)) + m log n + n log m) time.
