The initial solution to my problem is not feasible as -ve slack are present in the table. So I tried to remove them by the a process I found on YouTube. https://youtu.be/LE9Lnl2iXrA After a no of iterations the -ve slack variables are reduced but not gone fully, but the problem is I reached a point at which there are no +ve numbers in the row containing the -ve slack element. How do I proceed further. I also tried the 2 phase method with artificial variables. That too failed. The final table at which the problem starts is given here https://drive.google.com/file/d/19EbgR0yGUwNrFH8-uYYz6mPO7RflC7xo/view?usp=drivesdk
So where did I went wrong? Or do I need to use some other algorithm to solve this?
