TīmeklisWolfe duality. In mathematical optimization, Wolfe duality, named after Philip Wolfe, is type of dual problem in which the objective function and constraints are all differentiable functions. Using this concept a lower bound for a minimization problem can be found because of the weak duality principle. [1] TīmeklisFirst, we want to solve the Lagrangian dual program.
