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...
We are given an array of n points in the plane, and the problem is to find out the closest pair of points in the array. This problem arises in a number of applications.For example, in air-traffic control, you may want to monitor planes that come too close together, since this may i...
However, when d > 2 the problem becomes more difficult. Agarwal et al. [1] gave an algorithm to compute the bichromatic closest pair by exploiting the relationship they showed to exist between the bichromatic closest pair problem and the minimum spanning tree problem. Katoh and Iwano [18] ...
We conjecture that Closest Problem is NP-complete for DCJ and Reversal (signed) distances. How to improve the 2-approximation algorithm that computes all pairwise distances?. By the triangular inequality, a necessary condition for a string to be the center with radius at most d is that the ...

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.

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 ...
