WebbMETHOD To find optimal solution of any LPP by an alternative method for Big-M method, algorithm is given as follows: Step 1. Check objective function of LPP is of maximization or minimization type. If it is to be minimization type then convert it into a maximization type by using the result: Min. = - Max. . Step 2. WebbThe concept of multiple optimal solutions is associated with the linear programming problems. The multiple optimal solutions will arise in a linear program with more than one set of basic solutions that can minimize or maximize the required objective function. Sometimes, the multiple optimal solutions are called the alternative basic solution.
