Dear all Thanks to Kostas, we had a one-month extension for the paper submission. Even if the paper can be considered ready to be submit, we would like to use this time for further review. For this reason, the editors’ team (Pantelitsa, Nikos, Georgiana, and myself) will stop working on it, and everybody can read and review the content at the following link https://www.overleaf.com/7683596222xrkswsqhdpct Please add content if you think something is missing. We will definitively close the work on it the 15th of September, after that we will proceed with the submission. Best, Fulvio ____________________________________________ SESAR Lab - Computer Science Department Università degli Studi di Milano Via Celoria, 18 20133 Milano – ITALY Tel. +39-02-503 16381 http://sesar.di.unimi.it/ http://sesar.di.unimi.it ____________________________________________
