[GNNet challenge 2020] Correction in the instructions for the evaluation phase

Dear participants, We found a small error in the document with the instructions for the evaluation phase. Particularly, to generate the output CSV format with your solutions you can use the following pseudo-code: String = “” For node_src in range (19):     For node_dst in range (19): *If node_src != node_dst:*             String += str(delay[node_src, node_dst])+”;” # New sample, new line String +=”\n” This skips the node pairs where the source and destination match, thus resulting in 342 src-dst delay values (i.e., 19 sources x 18 destinations = 342 values). Please find attached a new version of the instruction document fixing this error. Also, to help you validate the format of your submission files, I attach a ZIP file with the expected format when applying a solution to our toy validation dataset (https://github.com/knowledgedefinednetworking/RouteNet-challenge/tree/maste…). Note that in this case the results correspond to a 17-node network, so we have 17x16=272 src-dst delay values per line. However, with the final test dataset we should expect 342 values per line. *I would like to take this opportunity to encourage you to register on our evaluation platform in advance to avoid potential problems before the evaluation phase starts **(October 1st)**.* Best regards, José Suárez-Varela Barcelona Neural Networking center Universitat Politècnica de Catalunya
