Thus, when a point is inserted in one of a pair of the b-Rdnn trees, a nearest-neighbor query must be performed. They showed the superiority of their method w.r.t. the two mentioned above when the two data sets present a high degree of overlap, where the overlap of two data sets...
We study the Closest Pair Problem in Hamming metric, which asks to find the pair with the smallest Hamming distance in a collection of binary vectors. We give a new randomized algorithm for the problem on uniformly random input outperforming previous approaches whenever the dimension of input point...
If there is a universal breakpoint on the right of the pair a,b (or b,a), then we apply a transposition such that the first block starts at position 4i−3 and ends at the element before the pair a,b (or b,a), and the second block ends at the universal breakpoint. – If ...
closest paircomputational geometryWe improve the famous divide-and-conquer algorithm by Bentley and Shamos for the planar closest-pair problem. For n points on the plane, our algorithm keeps the optimal O(n log n) time complexity and, using a circle-packing property, computes at most 7n/2 ...

As a second step, we extend our LSB technique to solve another classic problem, called Closest Pair (CP) search, in high-dimensional space. The long-term challenge for this problem has been to achieve subquadratic running time at very high dimensionalities, which fails most of the existing ...
Currently Tiny is learning Computational Geometry. When trying to solve a problem called "The Closest Pair Of Points In The Plane", he found that a code which gave a wrong time complexity got Accepted instead of Time Limit Exceeded.
