  • If your assignment 2 mark is low

    Posted by Raymond Wong Monday 22 October 2018, 01:29:02 AM.

    Please check the video of the last lecture first. I have been receiving several emails asking if it is still possible to pass the subject even they try hard for the exam... You can find the answer from that lecture.

  • Assignment 2 results have been sent to your CSE email account

    Posted by Raymond Wong Sunday 21 October 2018, 10:50:17 PM.

    If you find some discrepancies between your marks and the test results (using a2-test/autotest yourself), please come to see us in our consultation hours.

    The fastest bwtencode is from Peng Ban (total 16.32s for the 7 tests), congratulations!

    The fastest bwtsearch is from Christopher Pollock (total 0.87s for the 67 tests), congratulations!

  • Assignment 2 marking tests

    Posted by Raymond Wong Thursday 18 October 2018, 12:59:11 AM.

    Tests used by auto marking for assignment 2 are now available on CSE linux machines.

    Similar to the simple sanity checking script posted previously, to run these tests , simply go inside the folder that contains your submission source code and makefile, type

    ~cs9319/a2-test/autotest

    It will run through 7 tests for encoding and 67 tests for searching. Note that this script does not handle the runtime timing and memory/storage usage checks.

    If you are interested in checking the timing and memory/storage usages, you may refer to each test listed in the file

    ~cs9319/a2-test/README.txt

    which lists all the tests from the above autotest one by one. You can then test them one by one, or test a particular one in details if you wish.

    I'll discuss the final results, statistics, and feedbacks in the lecture later today. Your marks (calculated from the correctness from the above tests, after the timing and memory checks) will be emailed to your CSE account over this weekend.

  • Tue consultation hour 10-11am at Rm213, K17

    Posted by Raymond Wong Sunday 07 October 2018, 07:07:34 PM.

    Hi, as mentioned in the lecture, there will be a special consultation hour on Tue morning. This is for the last minute Q&A before your assignment 2 due (hopefully you don't need it).

  • Assignment 2 new due date: 9th October

    Posted by Raymond Wong Tuesday 02 October 2018, 03:23:11 PM.

    We're still waiting for the investigation results from ss. However, we have checked numerous times this morning that the valgrind results were back to normal (numbers were not inflated). By considering the possible impact of this issue, the assignment 2 due date has been extended to 23:59 October 9, 2018.

  • Strange results from valgrind

    Posted by Raymond Wong Monday 01 October 2018, 01:26:51 AM.

    A few of you have reported some strange results from valgrind these few days.

    I'm planning to extend the assignment due date, and will announce the exact new due date as soon as we receive the investigation results from the sysadmin.

    This notice is to keep you informed about the situation.

  • Assignment 2 sanity check

    Posted by Raymond Wong Monday 24 September 2018, 01:55:41 PM.

    A simple bash script, as a sanity check, is available on CSE linux machines. It doesn't measure running time, memory usage, file sizes, nor any serious testing of your software correctness. In the actual final test, we will also check your code to ensure that BWT encode and BWT backward search are implemented, as required by this assignment.

    To run the script, simply go inside the folder that contains your program source and makefile, type

    ~cs9319/a2/autotest

    Then you should get the following output:

    Running encoding test...

    Encoding of test1.txt seems fine

    Encoding of test2.txt seems fine

    Running search test...

    Search 1 passed

    Search 2 passed

    Search 3 passed

    Search 4 passed

    Search 5 passed

    Search 6 passed

    Search 7 passed

    Search 8 passed

  • The fastest assignment 1 solution

    The fastest solution is from Christopher Pollock, congratulations!

    You can find his solution by login to CSE linux and cd ~cs9319/a1-test/winner

  • Assignment 1 marking script

    Posted by Raymond Wong Tuesday 04 September 2018, 08:17:09 PM.

    Tests used by auto marking for assignment 1 are now available on CSE linux machines.

    Similar to the simple sanity checking script posted previously, to run these tests , simply go inside the folder that contains your submission source code and makefile, type

    ~cs9319/a1-test/autotest

    It will run through 9 tests for encoding, 9 tests for decoding, and 20 tests for searching. Note that this script does not handle the runtime timing and memory usage checks.

    I'll discuss the final results, statistics, and what to do if my result is poor, in the lecture this week. Your marks (calculated from the correctness from the above tests, after the timing and memory checks) will be emailed to your CSE account on Thursday.

  • Disc quota

    Posted by Raymond Wong Tuesday 04 September 2018, 02:02:43 PM, last modified Tuesday 04 September 2018, 02:03:03 PM.

    I thought it would be useful to have more disc quota for your assignment 2 testing. An extra 800MB disc quota has been added to your CSE account.

  • Assignment 2 Spec

    Posted by Raymond Wong Thursday 30 August 2018, 02:59:40 AM.

    Assignment 2 spec is available. We will go through it briefly in the lecture this evening.
