Welcome to the Coding Arena

The Coding Arena is a Panaxeo tradition. Every year, we measure our egos coding skills. For the third time in forever, it’s open to the public! You are very welcome to enter!

This year is all about a helicopter we found in Gelnica. Your task is to find the most efficient flight path so that the helicopter can play our music to as many people as possible before it hits the mileage limit. Sounds fun? Read on.

How to play?

At a scrapyard in Gelnica, we’ve found an old chopper. We’re in luck, as it still has 1,500 km of flight before its regular roadworthiness (airworthiness?) test. It most certainly won’t pass.

So, we’ve attached a loudspeaker to the chopper. Our CEO has just released his latest folk music album; we need as many people to hear it as possible.

That’s where you come in! Help us draft the most efficient flight path so that as many citizens of Slovakia can listen to good music as possible. Use AI or something, we don’t mind.


And when you win, we’ll let you listen to the album yourself!

Input

  • CSV file with all the towns in Slovakia, arranged by population.

  • CSV file with a matrix of flight distances between each town pair.

  • Mileage limit in km (1,500 km).

Solution

  • Flight path, i.e., a series of locations separated by commas in the order in which the helicopter should fly (e.g., "Gelnica, Bratislava, Košice, Gelnica").

  • The start and end of the flight are at the scrapyard in Gelnica. The route can have a maximum of 200 stops (including the first and last town in the flight path).

  • The helicopter can fly over a given town multiple times, but the number of listeners is counted only on the first visit (i.e., only once 😊).

  • The mileage must not be exceeded; otherwise, the solution is invalid, and we don’t want any problems with the Air Police.


Additional info

  • You can code in whatever you want and however you want. Just like always.

  • Using AI, LLMs, etc. is… Allowed.

  • Please don’t hack the server. It’s from the same scrapyard as the helicopter.

  • You can submit as many solutions as possible; only your best one counts.

  • In case of a tie in the number of listeners, the shorter flight wins.

  • If the tie persists, the earlier submission takes priority.

The Deadline is on April 06, 2025 at 23:59 CET.

Frequently asked
questions

  • We want a level playing field for students and juniors. that’s why there are categories – juniors and seniors. There will be a winner in each of these categories.

    Not sure which one to choose from? Here’s a rule of thumb:

    – With less than 2 years of professional coding experience, pick the junior category.

    – With more than 2 years of coding experience, pick the senior category.

  • The Panaxeans have already had their internal run in the Chopper of Gelnica earlier this year. They can still participate, but their solutions will not count towards the official leaderboard. Wanna become a Panaxean?

  • ‘Cause it’s fun.

  • You can enter the Coding Arena at any point up to 6 April 2025.

  • No, we made it up.
