In a BIP problem, 1 corresponds to a yes decision and 0 to a no decision. If there are two projects under consideration, A and B, and either both projects will be undertaken or no project will be undertaken, then the following constraint needs to be added to the formulation:
A) A ≤ B.
B) A + B ≤ 2.
