% The goal of this script is to solve the Multi Commodity Flow Problem
% modified for Time Division Multiplexing ( TDM ) as seen in Contention
% Free Routing ( CFR ). The Multi Commodity Flow Problem is solved for the
% Concurrent Flow variant ( MCFP-CF ) with mixed-integer linear programming
% ( MILP ).
