WebThe focus of this lecture note is to learn primal dual method to solve linear programming problems. To show the approach, we will take the example of max-ow problem, it is closely related to min-cut problem. In the beginning, we will see the de nition of these problems and their formulation as a linear program. Webproblem called its dual. If the primal involves n variables and m constraints, the dual involves n constraints and m variables. The solution to either is sufficient for readily obtaining the …
