Even though there are such examples for different subjects, in TSP and VRP section only general formulations are given without any guiding example problems. Therefore, I am struggling to connect theory with practice. @A.Omidi $\endgroup$ – Repeating step 3 on the reduced matrix, we get the following assignments. The above solution suggests that the salesman should go from city 1 to city 4, city 4 to city 2, and then city 2 to 1 (original starting point). The above solution is not a solution to the travelling salesman problem as he visits city 1 twice.Radosław Hofman, Report on The Travelling Salesman Problem: A Linear Programming Formulation, 2008 1/5 Abstract —This article describes counter example prepared in order to prove that linear formulation of TSP problem proposed in [7] is incorrect (it applies also to QAP problem formulation in [8]).The origins of the traveling salesman problem are obscure; it is mentioned in an 1832 manual for traveling salesman, which included example tours of 45 German cities but gave no mathematical consideration.2W. R. Hamilton and Thomas Kirkman devised mathematical formulations of the problem in the 1800s.2

To get further in branch and bound, we need to find the cost at the nodes at first. The cost is found by using cost matrix reduction, in accordance with two accompanying steps row reduction & column reduction.
