Hello, Codeforces Community!

We are excited to introduce the GoForGold Long Challenges.

The long challenge format is where contestants are given a long period of time, usually a week or several days, to work on a set of problems. Some notable examples include CodeChef Long Challenges (discontinued) and HackerEarth Circuits (discontinued).

We will host GoForGold Long Challenges every month .

The duration will be ~10 days (from Friday afternoon to next Sunday midnight).

Why Long Challenges?

Short contests are fun, and almost all the recognized competitions are in this format only. The adrenaline rush they provide is what makes CP a sport, but there are some really good benefits of Long challenges :

  • Longer duration allows us to give contests in a much more relaxed environment.
  • We can attempt much harder problems as compared as we have more time to crack it.
  • There is a bigger room for learning a new algorithm, data structure, or some non-trivial trick or technique in a long contest.
  • As many participants are trying the same problems for 7-10 days, thus you have a larger community to discuss the problem.
  • The community is much more active because of the longer duration of the contest.
  • Many people miss the contests because of odd timing, clashes with their exams, etc in short contests but here everyone can participate as per their own convenience.
  • In a typical short contest, participants solve the problems which are easy for them in the first half and then solve the problems which really matter to them in the second half. In a long challenge you solve those easier problems on the first day and then spend the rest of the days on the problems which will challenge you.

This is a community driven initiative and all the problems are prepared/picked by the community. This is the first iteration and the problems will be a mix of old and new problems of varying difficulty level (800-2700). The nature of the problem will be educational and not ad-hoc.

We will also release topics and hints on day-7 so that participants will have 3 more days in which they can learn the concept and try the problem again. We will host the post contest discussion of the contest along with some learning sessions on the topics involved.

very fantastic!

Have you considered making future Long Challenges topic-based, similar to the DP contest on atcoder?

Hey guys! The contest is tomorrow and I just wanted to mention a few things.

Most of problems aren't original. We will try to have more and more original problems from February onwards, although it really depends on how many people are volunteering to help. We just had like 2-3 people who were giving problem recommendations this time. We also only had like 10ish days to prepare the contest, so coming up with new original + hard + educational problems was difficult.

This also means that some of problems could be found by simply googling. Obviously, please don't do that. This contest is purely meant to be educational and you're not even gaining internet points if you cheat. So we request people not to actively try finding the original problem. If you do come across the original problem, just don't read the editorial.

Again, this contest is purely meant for you. We just want to introduce you to newer kinds of problems and techniques, how you benefit from the contest is upto you.

We will also have a detailed Post-Conest-Discussion of the problems where we will discuss the concept and techniques involved in the problems and you will only get the maximum out of the PCD if you put your honest effort. Remember long challenges are different, the level of problems may be higher so don't give up after giving 1-2 hours on a problem. In short contests it's highly unlikely to solve problems of more than +200 rating from your current level, but here you can try to brick on much harder problems.

Since this our first time as well, there could be some mistakes so we'd love to hear your feedback after the contest! I hope you guys enjoy the contest as much as we enjoyed preparing it.

Good luck!

My submissions are stuck in queue while those who submitted after me had theirs judged. Is this a Codeforces bug?
