For a Traveling Salesman Problem instance with 304 cities, there are approximately 2.3x106242.3 x 10^624 possible unique routes. This number is derived from the factorial growth of permutations, specifically (304-1)! / 2, accounting for the fact that the starting city and direction do not matter for undirected cycles.

Conditions: The problem has 304 distinct cities.; Routes are considered as unique Hamiltonian cycles (direction and starting point do not matter).

Meet the concept

↗

The Traveling Salesman Problem (TSP) is a classic optimization problem that asks for the shortest possible route that visits a given set of cities exactly once and returns to the starting city. For an instance with 8 cities, there are 5040 possible routes.

Conditions: The route must visit every city in the set exactly once.; The route must return to the starting city.; The goal is to minimize the total distance traveled.
