A) require the use of greater-than-or-equal-to constraints.
B) restrict the decision variables to positive values.
C) restrict the decision variables to negative values.
D) do not restrict the sign of the decision variable.

Question

Quizplus · Accepted Answer

Non-negativity constraints require that the decision variables cannot take negative values, hence they must be restricted to positive values. Greater-than-or-equal-to constraints are only used if there are specific numerical bounds on the decision variables.
