WebSolve the following linear programming problem by applying the simplex method to the dual problem. It allows you to solve any linear programming problems. . The general form of an LPP (Linear Programming Problem) is Example: Lets consider the following maximization problem. Each line of this polyhedral will be the boundary of the LP constraints, in which every vertex will be the extreme points according to the theorem. Finding a minimum value of the function, Example 3. eg. 1 { negative number. to maximize or minimize the objective function. b 13? 2 This will require us to have a matrix that can handle \(x, y, S_{1}, s_{2}\), and \(P .\) We will put it in 0 Besides the mathematical application, much other industrial planning will use this method to maximize the profits or minimize the resources needed.
