Consider a problem involving selecting six projects represented by binary variables X1, X2, X3, X4, X5, and X6. a. Write constraint(s) modeling a scenario in which either project 2 or 6 must be selected, but not both. b. Write constraint(s) in which at most two of the six projects have to be selected. c. Write constraint(s) modeling a scenario where project 5 cannot be selected unless project 1 or 4 or 6 is also selected. d. Write constraint(s) modeling a scenario in which exactly two of the projects 2, 4, and 5 must be selected. e. Write constraint(s) modeling a scenario where project 1 cannot be selected unless projects 2 and 3 and 6 are also selected. f. Write constraint(s) modeling a scenario in which, if project 1 or 5 is selected, they must both be selected. g. Write constraint(s) in which exactly two of the six projects are selected. h. (Optional Bonus Question) Write constraint(s) modeling a scenario where project 3 cannot be selected unless either project 2 or 4 is also selected, but not both.

Assuming W1, W2, and W3 are 0-1 integer variables, the constraint W1 + W2 + W3 is often called a multiple-choice constraint.
Name three phenomena that can constraint adaptation and for each constraint, how one may address each phenomenon experimentally.
