   • In case you do not have an account, you should send an email to       support@math.unipd.it        (and the teacher     luigi@math.unipd.it     in CC) asking for an "account to get access to LabTA" for the "Methods and Models for Combinatorial Optimization" course unit, specifying:
     • last name
     • first name
     • "Codice Fiscale" or "national identification number" (if available)
     • institutional email with domain "@unipd.it" (if available)
