Dear participants, We are sorry to see that some teams experienced problems to submit their solutions to the BNN platform during the last day. Consequently, we have decided to extend the evaluation period by one more day. The new deadline to submit solutions is: *Oct. 18th at 11:59:59 AM CET*. Please, note that this is a hard deadline. In case some of you experience issues again with the platform, you are encouraged to send the submission files (in ZIP format) to the following email, and we will check them manually later: gnnetchallenge(a)bnn.upc.edu Please, use this only as a fallback in case the platform fails. We will consider all submissions before the deadline that comply with the limitation of max. 5 submissions in the last 24 hours, or 20 submissions in total. In case of receiving more submissions, only the first submissions up to these limits will be considered. Apologies again for the inconvenience, and good luck! Best regards, José Suárez-Varela
