I want an app that generates 50 random destinations in the world with a route.

I want my phone to suggest a trip where I get to visit 50 different cities all around the world. <br><br>I should be able to filter the length of the trip but also the countries. <br><br>And the route need to be optimized so I’m not crossing the same country by a few cities. <br><br>If I’m in Paris, I should go to the next one, for example, Lisbon, even if it’s not the closest airport.
