Hii....Today our topic is traveling salesman problem. In this video we are going to solve an example related to TSP in operation Research.
The Traveling Salesman Problem (TSP) is a problem in combinatorial optimization studied in operations research and theoretical computer science. Given a list of cities and their pair wise distances, the task is to find a shortest possible tour that visits each city exactly once.
Two conditions of TSP is a salesman visit each city once. No city can be visit twice and visit to city i to i is not permitted.

Excellent lecture sister thank you so much
thanks mam👍 pls make videos of Transportation loop problem
Awesome ✌️
Thank you so muchh mam🥰
Amazing mam🙏🏻

mam bahut achha padhati ho ap
Thank you mam... Happy navratri ☺️🙏🏻
Superb
Wonderful explanation ma'am...
Thank you ☺️
Thank you ma'am
Very good explain the topic
Thanks mam
Really fantastic explanation
Good teaching method
Thank you ma'm and plz make video series on inventory plzzz
Mam please it is a kind request to you for making a playlist on Non linear programming problem
hello ma'am , i have a doubt --> At 12.04 why didn't you draw lines of that table and modify it ? why did you take the other already drawn table at 12.29?. we are supposed to edit the current table right?
Same doubt ma'am.
Please can you share topic of multicommodity in transportation problem with example
Ohh sorry 11:19😅 but well explained 👍🏻
In the step after the columns reduction matrix, we are drawing two horizontal lines & two vertical lines. Why can't we draw 4 horizontal lines, even that is covering all zeros. If horizontal rows are covered, in the next step, we will not be able to find the matrix based on uncovered elements. Could u please explain how to find a solution for this Mam?
th-cam.com/video/XqypICnZ-PA/w-d-xo.html
is anyone had cleared this doubt as i had also same problem plz help how to select which one to cover or not?
There is no problem any way you can draw the lines but keep in mind that all zeros should be covered. This will not affect the cost. The cost will be the same.
We will create the modified matrix with the help of these lines and after that we will create the assignment by selecting the minimum element and repeating this procedure till we get the optimal solution to the traveling salesman problem.
@@anivartakjainif we cover all elements of the problem then we will not able to find the lowest element in the question to make the solution optimal
Thank you so much mam 😊
Thanku madam ji
Mem aap kitni awesome 😝 hai ! Thank you
Fantastic 👌👌👌
th-cam.com/video/XqypICnZ-PA/w-d-xo.html
Thanks madam. Beacause of you i have completly understand the TRANSPORTATION MODEL AND ASSIGNMENT MODEL. I have a request to you madam. Please make video on QUEING MODEL and INVENTORY CONTROL.
Mam plz do games with saddle point method problems
Good video 🌹🌹
Please refer my channel operation research playlist
Excellent mam🎉❤
Thanku so much ma'am 💓
Very very thanks mam
Tq sis I passed becz of u 💥💥
Thank you man 😊
Best
13:51 D row me second wala zero kaise ho gaya ?????
Superb 😊
Thank you maim 🤗
Mast this is last class of assignment problem
Mam this is last class of assignment problem
17:08
Isme 4 ko asign kar k row or column dono k zero cancel kyo kiye...Kabhi sirf row k zero cancel karte ho or kabhi row column dono k...kaise ??
Very nice 👍
One video on air crew problem
Mam can u do cutting plane method of TSP
Thank you madam😍🙈
Supbb mam
mam is the method same for both minimization and maximization problems? also, is it mandatory that the salesman has to go in an certain order only, like from a to b and b to c and then c to d?
Is liye apki ye method rong he to.please fir solution ka video banaye ya to fir iska solution bheje
KYA HUM ISKA USE DAA(DESIGN ANALYSIS OF ALGORITHM MEIN BHI KR SKTE H KYA ??
Thnks🧐
Good 👍
Mam plz chapter linear programming bhi uplod kroo all types
Nice 👍👍👍👍
Is u r using nearest neighbour method?
WE CAN ALSO CUT THE FIRST 2 ROWS AND FIRST 2 COLS IN THE VERY FIRST TABLE AND WE LEFT WITH MATRIX INFINITE 4 AND NEXT ROW 4 AND INFINITE THEN WE CHOOSE MINI VALUE IE 4 AND SUBTRACT IT FROM THESE VALUES AND THEN WE GOT THE ANS A-B-C-D-A.
after column reduction if i use all horizontal lines to cover all zeros then how will we make the next modified matrix
as all the values will fall on line please explain
Same question 😅

Mujhe kuch samjh me nahi aa raha mam ....kal mera semester ka exam hai 😤😤
