Question 5 - TSP
A drone delivery company must deliver packages to five floating islands in a futuristic archipelago. The islands are named Aqua (A), Bora (B), Coral (C), Drift (D), and Echo (E). Distances (in km) between islands are shown below:
To minimize battery usage, the drone company decides to plan its route using the Christofides algorithm to approximate the optimal Traveling Salesperson path.
What is the approximate minimum total distance the drone will travel to visit all islands once and return to the starting point?
A) 24 km
B) 25 km
C) 26 km
D) 27 km
E) None of the above
Original idea by: Jhonatan Cléto

Boa questão, mas, dependendo de como se faz a tour euleriana e da ordem em que são eliminados os vértices, o algoritmo de Christofides pode dar resultados diferentes.
