Thank you so very much. Straight on point, elaborate and easy to understand. Our professor made a million mistakes in the 1 or 2 incomplete examples he tried to explain and it was so messy, even he was unsure and said that we should look at it at home and come back with questions, if we had any. This video has been a delight.

12:06 x1 chosed as entering column because its the only one that has negative coefficient, what if there is 2 column that has 2 negative coefficient?

do you explain why we need the 2-phase method for this problem? I guess because we have artificial variables.
@FadeStrategy Жыл бұрын
Artificial variables are introduced in order to find a feasible basic solution that we can start phase-2 with in order to find the optimal basic solution

what can you say, when you actually find a bounded solution ? Is it the same kind of answer as if it was a regular simplex method ?

Hey. Great video! I have one question regarding completing phase 1, does objective needs to be 0 in order to proceed to the next phase?

If it's a minimisation problem as opposed to a maximisation problem, are the auxilliary variables then maximised? Or are they always going to be minimised no matter what? Thanks
@sergiybutenko Жыл бұрын
The purpose of the auxiliary problem is to find a feasible solution of the original problem. For this purpose, we minimize the sum of artificial variables, regardless of the objective of the original problem.

I believe you can mix step 1 and step 2. I've never seen anyone separate step 1 and 2 like that.

In order to get proper temporarily obj. function at step 0 you can just sum up all the rows with artificial variables, revert the sign and place it in z row with artificial columns in that row set to 0.
