Step 1
In the case of 18 cities, there are 18! (18 factorial) possible permutations, which is equal to 6,402,373,705,728,000. This means that there are over 6 quadrillion possible routes to consider. Calculating the distance for each of these routes would require a Show more…

Consider the traveling salesman problem with 5 cities. You can start solving this TSP by using the branch and cut algorithm, initially focusing on the assignment type constraints. Let's say the optimal solution has the following 2 subtours. Find the subtour elimination constraints that will eliminate this particular solution.

Suppose we were faced with solving the traveling salesperson problem in a context involving 15 cities in which any two cities were connected by a unique road. How many different paths through the cities would there be? How long would it take to compute the length of all of these paths assuming that the length of a path can be computed in one microsecond?
