| Question 1 |
Given the following statements with respect to linear programming problem:
S 1 : The dual of the dual linear programming problem is again the primal problem
S 2 : If either the primal or the dual problem has an unbounded objective function value, the other problem has no feasible solution.
S 3 : If either the primal or dual problem has a finite optimal solution, the other one also possesses the same, and the optimal value of the objective functions of the two problems are equal.
Which of the following is true?
S 1 : The dual of the dual linear programming problem is again the primal problem
