Summary: If moments of singular measures are passed as inputs to the entropy
maximization procedure, the optimization algorithm might not terminate. The
framework developed in [M. Budišić and M. Putinar, Indag. Math., New Ser. 23, No. 4, 848–883 (2012; Zbl 1261.49012)] demonstrated how input moments of measures, on
a broad range of domains, can be conditioned to ensure convergence of the
entropy maximization. Here we numerically illustrate the developed framework
on simplest possible examples: measures with one-dimensional, bounded
supports. Three examples of measures are used to numerically compare approximations
obtained through entropy maximization with and without the
conditioning step.
