Mixed integer programming.

are not then the problem is a mixed integer programming problem.Thecase where the integer variables are restricted to be 0 or 1 comes up surprising often. Such problems are called pure (mixed) 0-1 programming problems or pure (mixed) binary integer programming problems. 2Simple example of mixed-integer linear programming. To formulate the problem, first decide on the control variables. Take variable x(1) = 1 to mean you purchase ingot 1, and x(1) = 0 to mean you do not purchase the ingot. Similarly, variables x(2) through x(4) are binary variables indicating whether you purchase ingots 2 through 4..
