Minimize the mean absolute deviation about the mean of the portfolio returns,
subject to achieving a target expected return.
M.A.D = sum( s: probability (s)*|ReturnOfScenario(s) - ExpectedReturn|)
Minimizing MAD can be done using linear programing
because one can linearize: d(s) =|ReturnOfScenario(s) - ExpectedReturn|
