I am trying to figure out the shortest path of going from location 1 to 10.
The path should start with location 1 and end with location 10 and go through each intermediate site (location 2-9) exactly once.
I have tried different ways (eg. Net flow etc...) to solve the problem but in vain.
I wonder what would be the method of solving it by using Simplex LP Solver/ Evolutionary Solver?

Below is the distance and my format so far.
