In this lesson we review the 4 special cases that can happen as we solve a LP using simplex methods. Then, we explain the Degenracy condition with an exmaple.

I can imagine the amount of hard work you had put in to make these awesome lectures!! And that hard work should be appreciated!! So on that note Thank You for this awesome Linear Programming playlist. Everything about the lectures is good(pace,content, explaination etc.)

I love your videos. I don't usually leave comments but your explanations are really nice, really thorough. I've personally watched this very video over 4 or 5 times just to refresh what I've learned. Thank you so much

Good explanation! But I have an issue with how you applied the Bland's rule and how I read it on Wikipedia (en.m.wikipedia.org/wiki/Bland%27s_rule). The Wikipedia version states that when choosing the column for pivoting (in the Z function), we should pick the "entering variable" with the lowest index. Sounds like in tableau 1, we should've picked -1( or X1) instead of -2( or X2). In other words we should not go by the most negative variable. Am I right or I am missing something? I would be happy if you helped get a good grasp on that one.

There is no tie for selecting the entering variable in Table 1. Entering Variable is chosen based on minimum Z value for the maximization problem. There is a tie for leaving variable in Table 2 as both current B.Vs correspond to same minimum ratio.

thank you for such informative video, I would like to know if I used a software, am going to get the same results in catching the specail cases,or the soft wares are not accurate sometimes.
@sxmirzaei7 жыл бұрын
you should get the same result for the most part if your problem is linear.

I am not sure about your questions. But there is only one degeneracy condition which is explained in this video with an example.

all Z values would be all zero and Cj-Zj value would be 1, 2 how ur Z value come to be -1 and -2???
@sxmirzaei7 жыл бұрын
If you are referring to the first table, it's because we standardize Z equation by bringing all the variables to the left had side i.e. Z-x1-2x2=0
