Linear Programming 5: Alternate solutions, Infeasibility, Unboundedness, & Redundancy

This video discusses special cases/situations that could occur while solving linear programming problems. Note that at 0:51, 2x + 6y = 2(x + 3y) and not ½(x + 3y)

• Alternative optimal solutions
• Infeasibility
• Unboundedness, and
• Redundancy.

Linear Programming 1: Graphical Solution -Extreme/Corner Points

Linear Programming 2: Graphical Solution - Minimization

Linear Programming 3: Graphical Solution – with negative coefficients

Linear Programming 4: Slack/Surplus, Binding Constraints, Standard Form

you are amazing :) you explained me in 20 minutes everything that my reacher could not in 2 months, thank you

[huascarhuascar]

you explained something that my professor in graduate school took 2 hrs to explain, you did it in 3:42. thanks

[muhammadobad]

My college is waiting my time and money without understanding anything from them, Your video is really very helpful.

Many thanks again

I spent 3 days forcing a Redundant constraint to work out. You have freed me from the confusion. Thanx

[hieunguyenquang]

you are truly amazing, I can't thank you enough, the way you explain it is so straightforward. thank you!!

My prof explaine this to us for 1h and we couldn't understand it properly, this video helps a lot! You explained it clearly.

Linear programming 5? More like "This video covered a lot of different cases; oh my!" Thanks again for making so many very highly-educational videos, and then sharing them.

[RahulSharma-jmfy]

thanks ...u made it so easy ..in my book this is in approximately 56 pages..and u share it only in 5 min ..thanks lot ..God bless you

[Samueljayapaulpandit]

Man...I dont know how to thank you... You are awesome... Keep going..you will be students fav.. Thanksss a lot

[namatakakautharah]

Wooow I ve learnt linear in 1 hour from your tutorials✌️

[theraphachukwu]

OH THANK YOU SO MUCH!! I'm going to pass my paper tomorrow for sure. God bless

[Greenide]

Thanks Joshua, I was looking for this! It was really helpful.

[dorothykhabenyanakgathi-th]

Thank you so much, this lesson made it easy for me to understand linear programming special cases

[speedbird]

Awesome!
topics well explained in short time which makes it possible for all us to watch

[RayRay-ytpe]

Thank you so much! You've gained a new subscriber.

Great video!! Excellent for last-minute revision!

[asadmujeeb]

great explanation, Joshua.!!! Thank you

[muhammadobad]

We should pay you for this,
Many thanks

In the unboundedness, the state is minimization

[IANgalaxyguy]

How do I show Alternate solutions, Infeasibility, Unboundedness, & Redundancy WITHOUT drawing a graph? I.e. algebraically
