## Contest parameters

The contest consists of 2 rounds:
* An elimination round, where entrants have to complete a five-hour challenge via the Deadline24 website.
* The finals, which lasts 24 consecutive clock hours.
The qualifying round lasts 5 hours and is conducted via the Internet. The teams receive tasks and necessary input data. The objective is to find the solution (in any way) and to transfer it to the verification server within a given time. The best 20–30 teams qualify for the final. The qualifying round is open for all the teams who have registered via Deadline24 website before the registration deadline. The final task of the contest consists of an appropriate interaction with the contest server under the terms and conditions specified in the task. Communication with the server is conducted using TCP/IP protocol. Participants work on their own equipment (the organiser provides one 230 V power outlet and one LAN RJ-45 jack or a plug-in cable for each team) and are allowed to choose any working environment and programming language. They may use any materials and auxiliary devices they bring with them, except for any devices providing access to external support. The access to any external help is strictly forbidden.
