WebStrong Duality. We examine the concept of duality in the context of a convex optimization problem. For any minimization problem, weak duality allows us to form a dual problem which provides a lower bound on the original problem. The dual problem is always convex (it is a concave maximization problem). We say that strong duality holds if the ...
