Ottimizzazione per il problem solving
L’esame si svolge tramite l'ausilio della piattaforma Exam (accessibile dalla propria pagina studente, nella sezione “Esami in remoto”, 30 minuti prima dell’inizio dell’appello a cui si risulta iscritti). Il software Respondus viene utilizzato per garantire l’inibizione di qualsiasi software oltre al browser sul proprio computer.
L'esame prevede, analogamente a quello in presenza, una domanda relativa alla modellazione di un problema di ottimizzazione, e una serie di quesiti (a risposta aperta e/o multipla) relativi alla complessità computazionale e ai metodi di risoluzione di problemi di ottimizzazione continui ed interi visti a lezione.
Dotazione necessaria: un computer dotato di webcam, microfono, altoparlanti e accesso a internet. Sul PC deve essere installato il programma “Respondus LockDown Browser”. Il PC deve essere collegato alla presa di corrente per tutta la durata della prova.
Non è consentito l’uso di qualsiasi altro dispositivo elettronico, accessorio o periferica (es: auricolari, cuffie, smart watch, cellulari, schermi aggiuntivi, ecc.). Non è consentito l’utilizzo e la consultazione di libri, appunti o altro materiale. È tuttavia ammesso l’utilizzo di matite, gomma e righello. È anche possibile avere qualcosa da bere (es. bottiglietta d’acqua). Non è consentito alzarsi o allontanarsi dalla postazione per tutta la durata della prova.
L’esame deve essere svolto in un luogo silenzioso e correttamente illuminato della propria abitazione, privo di altre persone per tutta la durata della prova.
Viene invalidato il compito a chiunque, per qualsiasi motivo, non rispetti anche una sola delle regole citate o che sia scoperto (anche successivamente tramite l’ausilio delle registrazioni) in comportamenti non conformi ad esse. In base alla gravità dell’infrazione, il docente può decidere se comunicare tale comportamento alle opportune commissioni disciplinari d’Ateneo.
Ottimizzazione per il problem solving
The exam takes place with the help of the Exam platform (accessible from the student page, in the "Esami in remoto" section, 30 minutes before the start of the appeal to which you are enrolled), the Virtual Classroom and the Elaborati section (tab accessible from the main web page of the course). Besides, the Respondus software is used to inhibit any software in addition to the browser on the student computer.
The exam program and its structure remain unchanged compared to what is written in the Study Manifesto. Furthermore, due to possible complications introduced by the remote mode, the exam difficulty and length are reduced, so that it can be completed in one hour and a half instead of in two hours, as in previous years. The remaining hour, of the two and a half hours available for the exam, will be devoted to performing Phases I and III (see below).
• A computer (hereafter PC) equipped with a webcam, microphone, speakers, and internet access [will mainly serve to view the exam text]. The "Respondus LockDown Browser" program must be installed on the PC. The PC must be connected to the power outlet for the duration of the test.
• A mobile device, such as a mobile phone or tablet (henceforth CELL), equipped with a camera and internet access [will be used to interface with the teacher and for the final scan/upload of the homework]. An app for creating pdfs from camera images must be installed on the CELL (CamScanner is recommended). The CELL must be connected to the power outlet for the duration of the test. All on-screen notifications must be disabled (e.g., WhatsApp, Telegram, email messages, etc.).
• Pen and enough white sheets.
The use of any other electronic device, accessory or peripheral (e.g., earphones, headphones, smartwatches, cell phones, additional screens, etc.) is not allowed. The use and consultation of books, notes, or other materials are not allowed. However, the use of pencils, erasers, and rulers is permitted. It is also possible to have something to drink (e.g., a bottle of water).
The exam must be carried out in a quiet and adequately lit place in your home, free of other people for the duration of the test. The CELL must be positioned in such a way that a good and full camera frames the student's torso/face and position (hands and sheets). Furthermore, the CELL must not be reachable by the student when sitting at the desk. We recommend finding the best location in advance.
Conduct of the test
The conduct of the test, lasting a total of two and a half hours, involves the following steps in sequence.
PHASE I - Appeal and checks [maximum 40 min]
The student connects to the Virtual Classroom through the CELL within the time indicated for the exam, keeping the webcam and microphone temporarily disabled, and awaits the teacher's instructions. The invitation to the Virtual Classroom will be sent 30 minutes before the exam begins. The student also connects to Exam via PC, where the exam topic will be present (but will not be accessible because it is password protected).
The teacher starts the registration and carries out the appeal. The student who, for any reason, will not respond to the appeal within 15 minutes of its start will be considered "absent".
The teacher then interacts with each student (who will activate the CELL webcam and microphone). The student will be asked to:
• show a valid identification document
• show the compliance of the workplace and the surrounding environment
• position the CELL and stabilize the frame, which must be maintained for the whole duration of the exam. The CELL is muted, and the student sits at the station, waiting for the start of the test.
PHASE II - Examination procedure [1 hour and a half]
1. The teacher orally communicates the password to all those present.
2. The student starts the exam (this involves Respondus blocking the browser) and carries out the test.
3. At the end of the time, notified by the teacher, all students immediately stop writing. The student who finishes first must still wait for the deadline.
PHASE III - Loading the homework [maximum 20 min]
1. Upon instruction from the teacher, students stop the browser block (Respondus) on the PC and the audio/video streaming on Virtual Classroom from the CELL and access the Virtual Classroom via PC (with webcam and audio-activated).
2. Through the CELL, the student scans his/her assignment and uploads it to the portal in the appropriate "Elaborati" section (see the upload and format of the assignment). Students are advised to recheck by downloading it to the PC from the "Elaborati" section, that the uploaded file is readable, correct, and complete. If not, delete the old version and upload a new one.
3. The student, satisfied with its uploading, communicates it to the teacher. The teacher makes sure of the delivery and talks to the student that he/she is free to leave the Virtual Classroom, ending the exam.
Students, who for any reason, have not been able to upload their assignment will be considered "withdrawn". Only the parts of the homework delivered will be evaluated. Uploads/cancellations of assignments after the end of the exam will not be evaluated.
Other important clarifications
Homework upload and format
Each sheet of the assignment must include the student's family name, name, and registration number. The student must upload ONE SINGLE FILE, in pdf format and named "FamilynameName.pdf", obtained by aggregating the photographs of the different sheets through a particular app (e.g., CamScanner).
The behavior to be maintained for the duration of the test
• the audio/video streaming both in and out of the CELL must be active;
• it is not possible to get up or move away from the position;
• it is not possible to contact/communicate with other people outside the teacher;
• no one must enter the student's room;
• it is not possible to use the CELL except during the initial control or final loading phases of the homework, and only for those operations;
• it is not possible to eat.
Maximum silence is recommended so as not to disturb other students. Anyone wishing to ask a question during the test can do so by specifying their family name and name first.
A student can withdraw from the exam at any time. In that case, however, the student must have the following behavior:
• communicate their decision to the teacher, who will notify the withdrawal. This decision will be permanent;
• must remain connected to the Virtual Classroom and comply with the above rules until the end of Phase II. At that point, the student must not upload any files and can abandon the Virtual Classroom.
The exam is invalidated for anyone, for any reason, who does not comply with even one of the rules above or who is discovered (even later with the aid of the registrations) in behaviors that do not comply with them. If these violations occur during the test, students must withdraw at the request of the teacher, and they must behave as in "Withdrawals".
Based on the gravity of the infringement, the teacher may decide whether to communicate this behavior to the appropriate University disciplinary commissions.
Students who request Special Needs will have 30% more time (therefore, half an hour more) available for the test. In any case, at the end of PHASE II, those students will also temporarily stop writing, so that the teacher can devote himself to the delivery by the other students, and they are not disturbed by these operations. Once the delivery is over, and silence returns, those students can resume their test.
For any emergency during the exam, students can call the following mobile numbers:
Prof. Roberto Tadei 335 6604376
Prof. Daniele Manerba 339 5454453.
At least 48 hours before the start of the exam and not earlier than 7 days from the day of the exam, students enrolled in the exam must upload a file in pdf format on the course portal under "Elaborati", called "SurnameName_codeofhonour.pdf" , containing the form "CODE-OF-HONOR-STATEMENT ON WRITTEN & ORAL EXAMS IN REMOTE MODE", duly completed and signed. Students who do not upload the file within the scheduled time cannot take the exam.
As usual, students will receive notification of the test result via the portal. At the same time, the date and time of the vision of the homework will be communicated, which will take place through Virtual Classroom.
The registration of the exam will immediately follow the vision of the homework. Students, who wish to reject their mark, even after viewing the assignment, must communicate it by email to Prof. Tadei (firstname.lastname@example.org) by the date of registration.
