Abstract:

In this paper, problems of evenly spaced configuration of points on the sphere are discussed. After introducing the minimax optimal problem and the minimum energy problem on the sphere, a new method of obtaining an optimal configuration is proposed under an utterly different principle. The new method is called a spherical adjustment method. It is first shown that the spherical adjustment method is useful for generating a global optimal configuration of a small number of points. Then, it is shown that the new method is also useful for generating local optimal configurations of points for a wide range of the number of points. It is also shown that, by carefully selecting a good configuration as an initial condition, our new method is able to improve the equilibrium configurations of points, for instance, which are generated by Markov Chain Monte Carlo method under a repulsive interaction potential.
