current tableau of a maximization problem with slack variables Let the following S1, S2, S3 z X1 X2 X3 S1 S2 S3 RHS 1 0 a b 0 0 m 0 1 d e f 0 n 0 1 0 0 g h i 0 0 0 0 k 0 1 p a) Let a=0, b=3, c=5, is the solution optimal? If X2 enters the basis does the objective function value change? Why? b) Let x2 is entering the basis and sz is leaving the basis. Let n=3, o=6 and p=0. In the new tableau it is seen that the value of m is same. Why do you think the objective function value did not improve
