Challenge #1

Behind this year's first window is a classical optimization problem. When the number of cities grows, it gets exponentially more difficult to solve. Give it a try, either by finding the route yourself, or by implementing an efficient algorithm to solve the problem!

You are selling Visma software and need to visit 6 promising customers in cities b-g. You start from your home city a, and you also need to end in your home city a. 

From a city, you may only travel to the next one if it is connected with an edge/line. Each time you travel, you spend some time, equivalent to the number on the edge/line. You also don’t want to visit the same city twice.

Find the quickest way to visit all promising customers, while adhering to the above requirements.
