Since the preferences in these simulations are based on distance, in
my experience it is so rare as to be unnoticeable that there are either
Condorcet cycles, or disagreements between Condorcet and the social
utility winner.

Assuming minimum Bayesian regret is the same as minimum average distance
(and highest utility), yes, it's a Voronoi diagram.

My sim can make some pictures like that.
