Hello students myself Dr. Gajendra Purohit and I have done my Phd in algebra and I have also cleared my CSIR-NET and my videos are for engineering mathematics and bsc students uploaded you all might face a lot of problem as many students ask that where are these videos so please if you are facing any problem then here is a playlist so you can go there as I have made separate playlist there so you can go there and watch my videos and if you are facing any problem
0:26
then you can go to the comment box and comment and students there might be some minute plus minus mistakes so please comment over there so that I can rectify that and I am going to add that in my pin comment also so that you know where I did the mistake so that you all avoid that. Students if you are preparing for CSIR-NET then you can go to the playstore and download the unacademy app and then search Gajendra Purohit and then follow me there so that for all my courses
0:54
you get the notification and do rate , review and share my course with your friends so that they also get the benefit of this
1:19
Hello students myself Dr. Gajendra Purohit and today I will discuss how with the graphical method linear programming problems are solved and students before this I had uploaded the videos which you can go and check on the I icon that on linear programming problem what type of videos I am going to upload and what this problem is that you can go and see plus for engineering mathematics and bsc students and IIT-JEM students who are preparing for that
1:43
or even preparing for GATE so here on the I icon and even students preparing for IAS, for them also there is good content available so you can go and watch my videos on the I icon so students I had told you that what are linear programming problem so
3:46
so students for terminology you can understand the definition from the book as there is no time to make you write the definition so I will directly explain that what is feasible region and what is optimal solution what is degeneracy, what is unbounded solution right? what is infinite solution , what is no solution but all this I will explain you so no need to take tension as everything will be covered so here
12:16
so in these types of cases the solution does not exists such solution are unbounded solutions, solution do exists but we call it as unbounded solution
12:43
so I will discuss one or two more questions with you and then we will finish this topic so students just now I told you the concept of unbounded solution so you all must have understood this and now I will tell you infinite solution and alternate solution concept. So now only I told you this question
13:47
this means that here the solution will not be unique , it will not be optimal solution but it will be infinite number of solution. Now you all must have a question that sir
14:21
clear. So these types of problems are either infinite solution or alternate solution and hence give there concept so now what will happen here is that
14:50
so this is something to keep in mind . OK? that whenever that two points you get same solution so the points in between that at that point will also give the same solution which means that at all these points the answer will be 6 so this will be infinite solution. Students when I will tell this question with the simplex method there I will tell you that with the help of the table how we will find with the help of simplex method table that this comes out to be an infinite solution
16:58
so for these types of problem the solution will be no solution so for this type of common feasible region where no answer is coming so the solution be will no solution so students now I will take one last question and then we will finish this topic.So students let's see the last question
23:07
so students the concept that I have taught you on linear programming problem that you must have understood and students after this the topic that I am going to take is on simplex method that how with simplex method we solve these types of problems and here on operation research whatever content is there I will cover up that plus the students who are talking about statistics and probability for that I will start uploading plus on statistics and dynamics
23:30
I am soon bringing a good content so students be with me thank you so much for watching my videos. Thank you . Thank you so much
