A number of students could provide correct answer. Some students set up a set of constraint like: x 1 – x 2 <= -3 + M(1 – y) When the constraint was set to be x 1 – x 2 = -3, the actual result could be less than -3. The constraint could not be set. Q 4. Most students demonstrated branch and bound method to solve integer programming problem....
