If we let x_{1} represent project 1 and x_{2} represent project 2 and we say that x_{1} and x_{2} are 0-1 integers (where a value of means the project was not selected and a value of 1 means the project was selected) then the constraint written as x 2 ^

If we let X; represent project 1 and Xa represent project 2 and we say that Xi and X2 are 0-1 integers (where a value of O means the project was not selected and a value of 1 means the project was selected) then the constraint written as x2
