0 out of 2 points

Incorrect
Rounding non-integer solution values up to the nearest integer value will result in an infeasible solution to an integer linear programming problem. Answer
Selected Answer: True
Correct Answer: False
Question 6

2 out of 2 points

Correct
In a 0-1 integer programming problem involving a capital budgeting application (where xj = 1, if project j is selected, xj = 0, otherwise) the constraint x1 - x2 ≤ 0 implies that if project 2 is selected, project 1 can not be selected. Answer
Selected Answer: False
Correct Answer: False
