Question about the deadline of preliminary test

I note that the test phase begins at Jan 25th and ends at March 1st. Will the preliminary test (validation) phase be closed during the test phase?

Dear Vision307,

Thank you for joining the challenge. The validation phase will stay open to test containers. Good luck!

Kind regards, Mark

Hello I noticed that the preliminary test phase has ended. Will it be reopened again?

Dear Challenge Organizers,

I hope this message finds you well.

I am writing regarding the validation phase. Based on your initial communication—“The validation phase will stay open to test containers”— we assumed that the phase would remain open for submissions. However, we recently discovered that the validation phase has been closed, which has prevented us from submitting our work. Best regards

Dear all,

You are all totally right. Due to the wrong initial configuration the preliminary test set was closed. I reopened the preliminary test set for further testing of containers. I am very sorry for any disturbances this may have caused. Good luck with the challenge!

Kind regards, Mark
