yes this is travelling salesman problem, but i just need the linear programming, not the solution

n = 12 c_ij= distance from city i to city j x_ij = 1, if a tour includes travelling from city i to city j 0, otherwise from here i don't know

the objective function would be the sum of all the miles for route \[O = \sum_{i=1}^{12}\sum_{j=1}^{12} x_{ij} *c_{ij}\] as far as the programming, not sure, it seems there are 11! possible routes so the goal is to use a bunch of loops to assign all 11! combinations to x_ij then evaluate each sum and determine the route that yields the minimum value

i read the final model for TSP, but in the decision variable there is y_ij=flow from node i to node j, should i use this too?

dumbcow Group TitleBest ResponseYou've already chosen the best response.0
yes probably, the decision variable y_ij will tell the program what to assign to x_ij sorry i haven't done too much with linear programming or graph theory

I'm sorry but this would take a bit too much detail for me to investigate right now. I am also quite tired (it's almost 3am here) so I afraid I'll have to pass you off @Zarkon @myininaya @Callisto @KingGeorge most of them are online right now, hopefully one comes and helps Good luck!
