Question $1$

A solution that satisfies one constraint $in$ a problem $is$ called $an$ optimal solution.

True

False

The expression $\frac{x+y}{y}100is$ a valid linear programming

constraint.

True

False

When solving $an$ integer programming problem, rounding the

solution $of$ its $LP$ relaxation $to$ the closest integer always

yields the optimal solution $to$ the original problem.

True

False
