Minimum-energy point charge configurations on a circular disk

Kari J Nurmela

Show affiliations


Stochastic global optimization methods are used together with problem-specific heuristics to find configurations of n equal point charges on a circular disk such that the potential energy is minimized. Previous such optimal or conjecturally optimal configurations have been published only for and n = 29,30,50. Earlier results are examined and the best currently known configurations - most of them new - for are presented.
