Additional information  This is a natural extension of the standard Markovitz MeanVarianceOptimization
(MVO) model by constraints for small investors. The variables in the standard
Markovitz model determine which fraction of the investment is made in the
repective assets. When the investment is bounded within a range that is not very
much bigger than the prices of the assets, one has to take into account that
each asset has a minimum unit of which only integer multiples can be traded,
e.g. 1, 0.1, or 0.01. Hence, the optimization problem for the small investor has
integer variables in addition to the budget constraints that define lower and
upper bounds on the investment.
