| # Understanding the leaderboard | |
| There are two types of leaderboards for all competitions: | |
| - Public Leaderboard: This leaderboard is calculated on X% of the test dataset, and is what you see on the competition page all the time. | |
| The value of X will be mentioned in the problem statement by the organizers. | |
| - Private Leaderboard: This leaderboard is calculated on the remaining (100-X)% of the test dataset, and is made public only after the competition is over. | |
| Your final ranking is based on the private leaderboard. | |
| When you make a submission, both the public and private leaderboard scores are calculated but only the public leaderboard score is displayed. | |
| When a competition is over, the private leaderboard score is revealed and the final rankings are calculated based on that. | |
| You can select N submissions to be considered for the private leaderboard score calculation. | |
| The value of N will be mentioned in the problem statement by the organizers. |
