Web3 The dual of the dual is the primal The following result establishes the dual relation between the primal and the dual. Theorem: The dual of the dual is the primal. Proof. … Linear programming problems are optimization problems in which the objective function and the constraints are all linear. In the primal problem, the objective function is a linear combination of n variables. There are m constraints, each of which places an upper bound on a linear combination of the n variables. The goal is to maximize the value of the objective function subject to the constraints. A solution is a vector (a list) of n values that achieves the maximum value for the obj…
