aye haye oyee hoye , aye haye oye hoye bado badi ❣💝, beautiful lecture
I've been watching all your videos lately, thanks Dr.
Many thanks....
Thanks sir your classes helps me a lot
thanks for the wonderful lecture.
Sir you have mentioned in notes at the end of the video that if a solution is feasible then it is optimal .But is it true always? we already get in unbounded solution ,where we have feasible solution but no optimal solution.
7:01 Sir is it possible for a inconsistent system to have a feasible solution.According to me it is right since I have taken the example x1+x2=1/2 and x1,x2>=0..am I right sir??
Yes... You have feasible region
Timing-9.40
Region in 3 quadrant , is common so it's is infeasible region or no feasible region.
Provided Xi≥0
Feasible region means "All those points which satisfy all Constraints and non-negativity restrictions such as x_i >=0". SInce at 9:40 time, the shaded region is 3rd quadrant and it does not satisfy the conditions x_1, x_2 >=0 and hence it is NOT FEASIBLE....
Remember, all those points which lies in the shaded region (3rd quadrant) are ONLY SOLUTIONs but NOT FEASIBLE SOLUTION......
Watch this lecture (th-cam.com/video/fT31HmNAXF0/w-d-xo.html) to more understand the difference between "SOLUTION", "FEASIBLE SOLUTION" and "OPTIMAL SOLUTION" with several examples
@@DrHarishGarg I watched it ,
If X1,X2
Yes.... It is true.... If x1,x2
I again ask the same thing again and again... Feasible solution means which satisfy constraints and restrictions on x1,x2. In example x1,x20.
For more details, you may contact me through my email id.
Doubt -
Is Feasible region is common region in 1 st quadrant
Or common region in any quadrant
Feasible region is not always in 1st quadrant.... It depends on the restrictions such as x_1, x_2 >=0 then 1st quadrant... If it is given as x_1 >=0, x_2
Firstly it was an Extremely helpful video sir 👏🙏thank u sooo much
Secondly ,can u plz let me know the name of book from which u have taken these questions??
Thanks for watching and appreciation and like.
Not any particular book... questions are designed by me own for this lecture... Anyhow, you may See the description for the book.
