Is have private data to calculate the final score?

In task3,could anyone please tell me what the Secondary Score is and whether there is any private data used to calculate the final score?

We don’t have private data.

We will re-test your submissions upon the end of the competition to rule out the impact of randomness, but the data will be the same.

Thank you very much for your reply!!!

I would also like to ask what is the Secondary Score

It should be something that is used to break ties. We won’t use that since it is highly unlikely to have exact ties.

Could you please clarify the details of re-testing the submissions to rule out the impact of randomness? Thanks!

Basically we will test your submissions under different random seeds. If your solution is (largely) deterministic, there should be nothing to worry about.
