Z* is Zmin, so the question is of Zmax which is -z*=Zmax=-18

Your concepts is very easy to know Sir and sharp full Sir so May God bless you and thanks a lot would you Sir!!!!!..…....
If we solve the original maximization problem using simplex, will it give the same result as the minimization problem using dual simplex?
I have a question
If dual problem is minimization should the sign be "greater than equal to" or "less than equal to"???
Same question I have
Sir please upload video on two phase method
Sir you are absolute teacher.... Thanks for teaching me....
Thank you sir
Good day sir. I am a bit confused.
In the video of primal to dual u said that dual is of minimization and constraints are >=
But here it constraints are changed to
Thank you so much for walking through this example step by step and helping us review! I think simplex problems can definitely get confusing, but you helped make things clear!
Very Useful!
Great video Sir. Understand now dual simplex with your very good explanation Sir, thank you.
great lessons, thanks a lot
tahnks man!! i got A++ S rated omgggg exam was so easy maaaaaannn dual simplex method just like me frfrfrrfrfrfr love oyumaaaan
Very helpful video 👍
from MU ?😂😂

Your the best teacher
14 ko exam h na
god bless you
its good
Good presentation & also easy to understand your language as it's local
This is Also called has Dual Phase method???? Correct?
at 2:30 the RHS is not positive so how can it be in standard form?
Sir what if dual problem is in minimum already, and right hand side is full positive ?
This scenario is unlikely because it will have no solution, the question is wrong
But do notice the = then you might be able to multiply it by -1 and the rhs may change and become negative
Then don't multiply z with -1 because it is already in minimization.
If it is in maximization then only we have to make a change.
@@MIHIRGOSAVI-.Kya baat hai 🫶
@@alakhjee8903bro tab bhi kya faida hoga...hme most negative to RHS mai dekhna h...aur tb bhi z ka RHA 0 hi to rhega ussey koi frk thdi na pdega
Explain better than my proffesor....i fully understand the concept🤩🤩🤩
forreal
what if ratio we find is not positive, anywhere
Hey man, fscing the same problem. Is the answer that we just have an infinite solution?
bro negative values are ignored
just ignored it
Unbounded solution

x3, x4 are not there
sir what is 1/2 /-1/2 you wrote there 1 but sir calsi shows -1/4 so which one to consider and why ?
-1/4 is right bro
(1/2)/(-1/2) = (1/2)*(-2/1) = -1
Use brackets while entering fractions in calc.
@@mohsindalvi87 finally pass the exam😪 math 4 is gone forever
@@Godarceus-x9i operations research subject is there in many universities' final yr and in mba also.
@@mohsindalvi87 operation research what is that ?
FRANKLY SPEAKING, THIS VIDEO IS CONFUSING ME. WHAT HAPPENS WHEN ALL THE RATIOS ARE NEGATIVES?
Recheck que bro, it must be already a minimization type.
