4 evenly distributed points on a sphere -Regular Tetrahedron, one of the 5 Platonic Solids- by means of simulated annealing [4 points répartis équitablement sur une sphère -le tétraèdre régulier, l'un des 5 solides platoniciens- par recuit simulé].
This set of 4 points is near the perfect solution (a tetrahedron).
