Hello, I have a test and I need help with one problem!! If we want to minimize a function, we change the sign of the variables and proceed as a typical maximization problem, BUT, if the coefficients of the original function are all positive, the change will make them negative... and in the first iteration, all the Cj-Zj will be negative!! (and there are no artifficial variables) So, how do I continue?? Should I pick the less negative Cj-zj?? Thank you, great lesson!!
this is good to learn, still this hand-method is not used anymore this is solved by EXCELL with the tool of Solver. believe me that is faster an accurate and solver gives the dual of the problem and its graphics.
that was great :) thnx Pr

but i'm extremely grateful for your posting a brilliant lecture series like this one, Sir.
You changed the attitude with which I viewed Operations Research.
You are an amazing teacher. Thank you Sir.

a lot of the lecture time is taken up by simple math... he should eliminate all this stuff just slows things down

41:40 In the 2nd iteration, he calculated Cj-Zj for X4 wrong. The result should have 2/5.
0-(-2/5) = 2/5
Still enjoyed it and learned a lot.

@cybern9ne I second the mistake at 41:40
These videos are a useful resource nonetheless
