An integer solution to a subproblem in the branch-and-bound method leads to a lower bound on the optimal objective value of the original problem. Now let’s look at the y 1 case. To solve this, we’d go back to the optimal tableau for the point (4;1:5), and add a row corresponding to the inequality y 1, or y + s 3 = 1. Then, proceed as we pantone stationery
