I need to make a constraint for the following condition:
Student 1 can only be on the team if students 2, 3, 4, and 5 are also on the team.
I'm not sure how to model this using equations. The equations must not have "and", "or", or "not equal to" signs in them. These equations are likely going to involve an M term in them (where M represents an arbitrarily large number).
I have defined binary variable $Y_i$ to equal 1 if student $i$ is chosen on the team and 0 otherwise.
Any help making the equations would be appreciated!
