Thank you all for your submissions in what has turned out to be and exciting and hotly-contested challenge. A number of concerns have been raised by the community about behaviour that is against the rules and spirit of the competition, and we take such accusations seriously.

As such, we will be delaying the reveal of the final leaderboard while we take the time required to fully review all necessary submissions and ensure that the best solutions win.

While the leaderboard states that it will be finalised by 8 June, this process may take a few more weeks to complete. If you are asked to submit your code for review (or for any other assistance), please help us out by doing so promptly. We thank you for your patience, understanding and cooperation with us during this time, and may the best model win!
