Weak duality. … WebFor any primal problem and dual problem, the weak duality always holds: f g When the Slater’s conditioin is satis ed, we have strong duality so f = g . The dual problem sometime can be easier to solve compared with the primal problem and the primal solution can be constructed from the dual solution. 12.2 Karush-Kuhn-Tucker conditions
