Python code. The travelling salesman problem asks the following question: "Given a list of cities and the distances between each pair of cities, what is the shortest possible route that visits each city exactly once and returns to the origin city?

Apply Genetic Algorithm to Travelling Salesman Problem $($TSP$)$ for the following Table. The table below shows the distances between each city in kilometres.

A fitness function calculates the total distance between each city in the chromosome's permutation.
