When the right$-$hand sides of two constraints are each increased by one unit, the objective function value will be adjusted by the sum of the constraints' dual prices.

A small change in the objective function coefficient can necessitate modifying the optimal solution.

If the optimal value of a decision variable is zero and its reduced cost is zero, this indicates that alternative optimal solutions exist.
