Consider there are 7 different projects a company can select. Let us call them projects A, B, C, D, E, F, and G Federal Law mandates that you must do at least 2 of the following projects: C, D, E, or F Select the option with that correctly states the constraint model form. C+D+E+F>= 2 C+D+E+F= 1 E>= 1 F>= 1 C+D+E+F
C+D+E+F >= 2
the above equaltion states that the sum of these four shoule be at least greater than 2 which means at least two will be selected.
