Question

max y = 0, and one or more artificial variables are present in the basis with zero-value at the end of phase i. We have found only a feasible solution of original lpp.

Answer 1

The value of the objective function. But this means that this variable has left the basis.

Now, As long as there is a positive variable you will do strictly better taking this one out of the basis instead of bringing a variable with value 00 ..✨❤✔️
