“pay” unnecessarily in the objective. So in this case, ξ_n = 0. Next, suppose that w · x_n + b = 0.2, so it is not big enough. In order to satisfy the first constraint, you’ll need to set ξ_n ≥ 0.8. But because of the objective, you’ll not want to set it any larger than necessary, so you’ll set ξ_n
