For the Big M method, explain why the simplex method never would choose an artificial variable to be an entering basic variable once all the artificial variables are nonbasic.
Answer to relevant QuestionsConsider the linear programming model (given in the back of the book) that was formulated for Prob. 3.2-3. Consider the following problem. Minimize Z = 3x1 + 2x2 + 4x3, Subject to and x1 ≥ 0, x2 ≥ 0, x3 ≥ 0. (a) Using the Big M method, work through the simplex method step by step to solve the problem. (b) Using the ...This chapter has described the simplex method as applied to linear programming problems where the objective function is to be maximized. Section 4.6 then described how to convert a minimization problem to an equivalent ...Consider the following problem. Maximize Z = 5x1 + 4x2 – x3 + 3x4, Subject to and x1 ≥ 0, x2 ≥ 0, x3 ≥ 0, x4 ≥ 0. (a) Work through the simplex method step by step to solve the problem.
