You can only start attempting the exam at 1:30pm AEST.

As mentioned in the last live lecture, we could only start marking a2 yesterday (after receiving all the submissions including those with special considerations). The progress is a bit slow, some submissions have been taking quite a long-time to run. We will email the result to you and announce it here asap, whenever the marking process is completed.
Meanwhile, to give you an estimate of your assignment performance (with some limitations as mentioned in the autotest's output messages), I have made a cutdown version of the marking test scripts with the same set of tests and you can:
1) log in to grieg and go to your folder containing the a2 code
2) run ~cs9319/a2/autotest
Following the instructions output from the script. Please post any questions in the Forums.
Please note that as I mentioned in the class, even if your a2 result is not good but your exam performance is very good, we will consider scaling your assignment score by manually re-checking and/or examining your assignment 1/2 code. If you have questions while you study for the exam, remember that consultation sessions are still available this week. Good luck.
Your final exam is scheduled for Monday 16 August 2021 13:30-15:30 Australian Eastern Standard Time (AEST).
Carefully read through the notes and instructions on the exam paper before you start.
If you have clarification questions, please email cs9319@cse.unsw.edu.au via a UNSW email account (in case external emails are filtered) during the exam.
Same as normal exam papers, this exam has been checked by at least one other staff member. We rarely got questions during previous COMP9319 exams, and if we did, the answer would usually be " the question is as it is written ". We're not expecting it to be any different in this exam.
The 2-hr exam paper will be released and available in Moodle .
I have made a sample exam paper available (in Moodle) to help you prepare for the exam. While most of its questions are just repurposing of some exercises or assignment questions, the main purpose of the sample paper is for you to get familiar with the exam format and style, so you can prepare and ask any general questions in advance (Please post your questions in WebCMS forum to share).
Details of the exam/sample exam and hints have been covered in the live lecture this week (Week 10). Please watch the lecture recording before you post any questions .
Please remember that consultations are still on for this week and next week (week 11), in case you have questions when you study for the exam.
I'll discuss some industry case studies / use of Web Data Compression and Search;
plus some last-minute help or hints for your assignment 2 (in case you are still having issues on speed / memory for small files).
A few students came to ask me about extending the time limit for decoding. Unfortunately, the time limit will have to stay the same (i.e., 90 sec of usr+sys time). However, your submission won't be tested for files larger than approx 32MB for decoding BWT. The spec has been modified to reflect this change accordingly (the last sentence in the Performance section).
I'll elaborate this in the live lecture tomorrow.
We have sent your assignment 1 result to your CSE email. If your have questions regarding your result:
1) Watch the live lecture of Week 7 on how to test your program using ~cs9319/a1/autotest
2) If it is in doubt, come to see Dominic in one of his consultation sessions:
https://webcms3.cse.unsw.edu.a<wbr>u/COMP9319/21T2/timetable
For the coming week, in case of many students seeing Dominic regarding a1, if you have other questions (e.g., fr the lectures, exercises or a2), try to see Adam instead.
Assignment 2 spec is available.
There are no consultation sessions next week (flexi week). If you have specific questions about a2 (or any other course-related questions), come to the consultations in week 7. There will also be a Q&A session during the live lecture in week 7.
Hi, there are a few questions asking what happens when the dictionary is full in a1.
We will follow the most basic LZW (not its variations) that has been summarized in the lecture slides: "Static after max entries reached". i.e., you can't add new entries to the dictionary anymore (but you can still refer to the entries that are already there.
I'll elaborate this more in the live lecture on Wed.
Please note that Assignment 1 is due next Monday ( 28th June 17:00 ).
Exercise 2 answers are released. If you have questions to work them out, please attend a consultation session.
Although exercise 3 has just been released, you have 2 weeks to work on it (there will be no new exercise for next week). So you can focus on Assignment 1 for now.
Assignment 1 spec is available (due: Monday 28th June 17:00) . It will be further elaborated in the live lecture this week.
Exercise 2 (adaptive huffman) is available. Answers for Ex1 are released. Please see us at the consultations if there are questions.
Exercise 1 is available now:
https://webcms3.cse.unsw.edu.au/COMP9319/21T2/resources/61237
We haven't covered LZW (i.e., Q3) yet, so please attempt Question 3 after the lectures this week.
Also, consultations start this week. If you have any questions from the lectures or exercises, please utilize the consultation sessions.
Welcome to COMP9319.
COMP9319 will maintain the same style and structure for this term, with the changes that there will be no tutorials. Instead, tutorial-style exercises will be provided, and many online consultations will be available to help answer questions regarding these exercises, lecture materials and assignment-related questions.
Lectures will be online, consisting of recorded video lectures and live online lectures on Blackboard Collaborate ( via Moodle ).
The first lecture on Wed 2nd June 14:00-16:00 will be live on Blackboard Collaborate , and I will go through how COMP9319 will be run and other course logistics. The lecture will be recorded, but it will be good to see you at the first lecture.
