What is the main purpose of introducing an artificial variable in the simplex method?
Correct answer: A. To create an initial basic feasible solution
- A. To create an initial basic feasible solution
- B. To increase the objective function value
- C. To remove a non-negativity restriction
- D. To convert a maximization into minimization
Explanation
Artificial variables provide an initial basis when slack or surplus variables cannot do so. The Big M or two-phase method later forces these temporary variables out of the solution.
