Closest Quadruplet of Points
By xeronix, 14 years ago, In English

I have solved closest pair and closest triplet problems using divide and conquer. I wonder if there is a problem ever asked which deals with finding closest quadruplet of points ( sum of distance between all pairs is minimum ) ? Also i want some efficient approach for solving similar problem for k-closest points.

CBR 82 DIV2 Problem E
By xeronix, 15 years ago, In English
Is centre of minimum enclosing sphere the answer to this problem ??

If yes then considering x and y coordinates only, can't we find minimum enclosing circle's centre and then somehow search for required z coordinate because min_z <= z <= max_z .
min_z = min. z coordinate in given set of points
max_z = max. z_coordinate in given set of points
