Answer:

The cheapest route to visit each city and return home again to Athens is:

A→B→C→D→A  or A→D→C→B→A.

Step-by-step explanation:

The Algorithm of Brute Force

  1. List of all possible routes
  2. Calculate the charge of each route found in Step 1
  3. Pick the route which has the cheapest route.

Let Athens ⇒A , Buford ⇒B , Cuming ⇒ C , Dacula ⇒ D

There are 6 routes to visit each city and return home again to Athens.

Route 1: A→B→C→D→A = 70 + 25 + 30 + 60 = $185

Route 2: A→B→D→C→A = 70 + 70 + 30 + 50 = $220

Route 3: A→C→B→D→A = 50 + 25 + 70 + 60 = $205

Route 4: A→C→D→B→A = 50 + 30 + 70 + 70 = $220

Route 5: A→D→B→C→A = 60 + 70 + 25 + 50 = $205

Route 6: A→D→C→B→A = 60 + 30 + 25 + 70 = $185

By checking the previous routes:

The cheapest charge will be $185 and it will be for the route

A→B→C→D→A  or A→D→C→B→A.
