# WORHP Kata of May 2023: Points on a sphere ⌚ 2023-05-01

A kata (in the context of programming) is a small training unit to practise coding. In this series of**WORHP Katas**we present standard problems of optimization which you can use to get familiar with optimization (and our optimization software WORHP).

**Kata:**We want to distribute 12 points on a unit sphere in . For each pair of points, we compute the reciprocal of their distance. Find the distribution which minimizes the sum of all these reciprocals!

*A solution will be provided with the next WORHP Kata.*

**Solution of last WORHP Kata:**For a line and a point we can find the perpendicular foot as

Using this CPP code and our solver WORHP, we get after 7 iterations:
