The tour group has three days remaining in Paris and the opportunity to do three cultural events. It is important to soak up as much culture as possible, so Saba decides to model this as a 0-1 integer program mandating that the group does three events
A couple of students object, not to the integer program, but to the set of cultural events that they have to choose from. They would rather have the option to do up to three events but perhaps only one or two and spend the rest of their time doing some "retail benchmarking." What was Saba's original constraint and how does that constraint change to cater to the whims of the students?
Answer: Saba's original constraint was E + L + S + B = 3, which directed the group to three tours. The new constraint is E + L + S + B ≤ 3, which allows for the possibility of no tours up to a maximum of three tours.
