Question

Which condition represents non-negative restrictions for two decision variables?

Options

• \[x\geq 0,\ y\geq 0\]

• \[x+y\leq 0\]

• \[x\leq 0,\ y\leq 0\]

• \[x-y=0\]

Answer 1

Non-negative restrictions state that decision variables cannot be negative. For two variables, this condition is written as \[x\geq 0,\ y\geq 0\].
