Multiple optimum solutions can occur when the objective function is _______ a constraint line. Question 2 options: unequal to equal to linear to parallel to
Homework Answers
Multiple optimum solutions can occur when the objective function is parallel to a constraint line.
Because multiple optimum solutions can't be achieved when constraints are parallel to each other.

True or False? 1. If an LP has multiple optimal solutions, then all solutions have the same objective function value (such as total profit or cost). 2. As long as all prices (objective coefficients) change within their respective ranges, the optimal solution of a linear program does not change. 3. When a dual price changes within its range, the optimal solution does not change. 4. The solution of a linear program always consists of whole numbers (integers). That is why...

You’ve been asked to develop a problem that can be used to explain some of the concepts you know to someone who has never heard of linear programming. 1. Formulate a maximization problem such that the following conditions are met (you may not use a problem has appeared on this assignment). Make sure to include all elements of formulation that we have discussed (i.e., objective function, constraints, non-negatives). a. LP problem with two decision variables (using X and Y as...
