Proggy-Buggy is a programming Olympiad organized by DataArt. It has been running since 2014, attracting over 10,000 participants from 60 countries. The competition, held twice a year, consists of 13 algorithmic problems that participants must solve within a 42-minute time limit.
The main protagonists of each problem are two creatures, Proggy and Buggy. Proggy is a highly skilled and creative being who writes programs, while Buggy can sometimes cause delays with errors that Proggy must work through. Navigating these obstacles can be challenging, but with patience and understanding, Proggy always finds a solution.
International Programming Proggy-Buggy Contest 2024
The Ultimate Question and the Contest Inspiration
The concept of a 42-minute time limit is derived from "The Hitchhiker's Guide to the Galaxy," a book by Douglas Adams. In the story, a unique computer named Deep Thought is programmed to answer the "Ultimate Question of Life, the Universe, and Everything" and provide the key to solving all the problems in the universe. After seven million years of continuous calculations, the computer finally revealed the answer: "42."
Another concept inspired by the book is the name of our Spring competition. It's called the Towel Contest and is held on Towel Day, celebrated worldwide every year on May 25th as a tribute to the author Douglas Adams by his fans.
It has become a tradition for participants to come to the May competitions with towels. A towel is the most helpful thing an interstellar hitchhiker can have because, as Douglas Adams writes, "Any man who can hitch the length and breadth of the Galaxy, rough it, slum it, struggle against terrible odds, win through and still know where his towel is, is clearly a man to be reckoned with."
Place and Time
The contest is held twice a year – Towel Day on May 25th and the Proggy-Buggy Contest on October 26th, 2024.

International Programming Proggy-Buggy Contest 2024
Participants Categories
In the Autumn contest, solo participants and teams of up to three people can participate. The Spring Contest is for solo participants only. In each contest, there are three different categories - experienced competitors, mid-level, and beginners.
The contest has three types of participants:
Amateurs
Participants aged 16 and above. May have competed in programming competitions other than international ones, such as university, city, regional, or national-level Olympiads (excluding ACM ICPC International Programming Contests or International School Olympiads in programming of any level).
Professionals
Participants in the National Student (ACM ICPC) or School (IOI) Olympiad in programming and other international programming competitions, but not finalists or winners.
Superheroes
Participants who ranked in the top 10 of the National Student Olympiad (ACM ICPC) or School Olympiad (IOI) in programming and past winners of the Proggy-Buggy Contest in all categories.
Contest Rules
- Participation is free
- The Proggy-Buggy Contest is open to everyone: whether you’re a student, developer, tester, or just love algorithmic puzzles!

- Categories for beginners and experienced participants.
- You need to register and create an account on the Contest Platform. For this, use the link and follow the instructions on the page.
- We will start the Contest after the final countdown on the YouTube stream. You will receive a link to it in the e-mail the day before the launch along with a link to the contest page. Be ready to join us on time and ensure you have a stable network connection
- All participants (solo and teams) will have 13 problems to solve and 42 minutes for their completion.

- Join us online from anywhere in the world (except the Russian Federation, as well as other sanctioned territories), or in-person at one of our DataArt R&D Centers or Partner Hubs.
- Before the contest you can take the opportunity to practice by solving tasks from the previous years’ contests. You can find them in the section “Training” on www.proggy-buggy.com
Winning Categories
The winner is the individual participant or team that solves the maximum number of tasks with the lowest penalty.
The penalty is the total time used to solve a task, calculated as follows: the total time is the sum of the time consumed for each problem solved. The time consumed for a solved problem is the time elapsed from the beginning of the contest to the submission of the first accepted run, plus 20 penalty minutes for every previously rejected run for that problem. No time is consumed for a problem that is not solved. These rules are consistent with the International Collegiate Programming Contest (ICPC).
We determine the winners in the following categories:
Additionally, we have these extra categories:
- Prize for the shortest correct answer to a problem with a solution.
- Prize for the first correct answer to a problem with no solution.
- Honorable Mention for the team or participant with the fewest penalty points.
Programming Languages and Compilers
To solve any problem, create a console application and select a programming language from the drop-down list.
You can use the following programming languages: C, C++, Free Pascal, Java, Mono C#, Python, Ruby, PHP, JavaScript, etc.
Once you've written your code, send the source text to the verification server for review. Remember that not all problems have a solution, and particular tasks may require a specific method.

How are the tasks assessed?
The tasks are assessed according to the ACM ICPC rules. The winner is the individual participant or team that solves the maximum number of tasks with the lowest penalty.
The penalty is the total time used to solve a task, calculated as follows: the total time is the sum of the time consumed for each problem solved. The time consumed for a solved problem is the time elapsed from the beginning of the contest to the submission of the first accepted run, plus 20 penalty minutes for every previously rejected run for that problem. No time is consumed for a problem that is not solved.
What if a task has no solution?
The solution to this problem is the participant's program, which should display the following text on the console: "UNDECIDABLE."
An example of such a program in JavaScript:
console.log("UNDECIDABLE");
A solution to an UNDECIDABLE problem is evaluated in the same way as a solution to any other problem (whether correct or incorrect).
Suppose a participant attempts to cheat by submitting an 'UNDECIDABLE' response to each problem (taking advantage of the permission to submit multiple solutions to the same problem). To prevent such tactics, attempting to classify a solvable problem as 'UNDECIDABLE' results in a penalty of '-1' for that problem.
For example, if a participant has solved problems A, B, and C at a certain point in time and attempted to solve problem D as 'UNDECIDABLE' (which was solvable), then the number of problems solved by the participant would be 2 (1 + 1 + 1 - 1).
If the participant later correctly solves problem D, the score for problem D will be adjusted to 0 (-1 + 1).
In an exceptional scenario, if a participant solved all 13 problems through guesswork, two of which were unsolvable, and subsequently solved the remaining problems correctly, the total number of problems solved would be 2 (2 + 11 * (-1 + 1)).
Is there a system of penalties?
Yes. There are two types of fines:
- A penalty for guessing a problem lacks a solution instead of solving it to confirm. For more details, see the What if a task has no solution section.
- A penalty as an integral part of the final score for the solved problem. For more details, see the How are the tasks assessed section.
When will the results be available?
Will the winners be chosen separately for teams and individual participants?
No. Winners will be determined in the categories: Amateurs, Professionals, Superheroes:
- Honorary 1st place (Team or Individual Participant)
- Honorary 2nd place (Team or Individual Participant)
- Honorary 3rd place (Team or Individual Participant)
Additionally, we have these extra categories:
- Prize for the very first correct solution to a problem.
- Prize for the shortest answer to a problem with a solution.
- Prize for the first correct answer to a problem with no solution.
- Honorable Mention for the team or participant with the most penalty points.
- Honorable Mention for the team or participant with the fewest penalty points.
