Challenge Rules


  • The problem is a part of AI Blitz 5. The problem will have a separate leaderboard and an associated weight. This weight denotes the problemโ€™s contribution to your final score. 
  • The final leaderboard will be determined by the weighted mean of the ranks of a participant/team across all the individual leaderboards. The organizers reserve the right to change the weight of a problem during the competition.
  • If a problem is not attempted by the participant, his/her rank in that problem is set to the total number of participants in the whole competition.
  • To help you "Get Started" we have a starter kit available for each of these problems. We hope they are helpful; if you find any bugs, typos, or improvements, please send us a pull request.
