## Announcements

12/06/06 A page of model answers to the three questions in
Assignment 2 are now provided for review purpose.
01/06/06 Additional consultations will be scheduled from the
week of 12 June. See Consultations below.
31/05/06 Please read announcement re examination below.
20/05/06 Last lecture is on Monday 5 June. Last tutorials are
in the week beginning 29 May.
08/05/06 If you wish to request a special consideration please
read the item below on the procedure to be followed.
06/05/06 Please note that the lecture slide numbers do not
reflect lecture sequences as from last week. The
rearrangment has been made so that material relevant
to assignment 3 can be covered in time for you to
begin work on it. The lecture slides have obvious
titles that signify their content, so look for them.
04/05/06 Assigment 1 marks will have one test corrected to
reflect the specs, and anyone who was wrongly marked for
that test will have it fixed. The worry about the marks
being counted as out of 12 rather than 10 is misplaced.
Marks for this assignment are out of 10 whatever the
display says. We checked this, and the bonus parts
were actually given marks above the normal ones.
On other matters arising from mail to cs2011.hw2, most
did not warrant answers to be posted to the FAQ. They
all seem to be the kind of questions that can be quickly
resolved at a tutorial. So, for hw3 can you please
raise such questions early at the tutorials, as we have
noticed that the nature of many questions indicate very
late starts on assignments and non-attendance at lectures
or tutorials.
28/04/06 Please read the posting in red below on Assignment/Exam
weights.
04/04/06 The FORUM postings are not to be taken as authoritative.
Watch the FAQs for that. Also, the FORUM is not to be
misused for stream-of-consciousness musings, nor broad
unfocussed gripes. It is meant for you to educate one
another on TOPICS RELEVANT TO THE COURSE MATERIAL.
30/03/06 Marking of assmt 1 will have 20% of the marks for
style.
27/03/06 Ignore any current tests that conflict with the decisions
below. In the actual test data that we will use for
marking the decisions will be respected.
26/03/06 Re the definitions on progressions for assignment 1
I have asked mathematicians if progressions like
[2 2 2 2 2] are arithmetic or geometric, and the answer
is that by definition "yes". However they add that by
convention if one says a progression is arithmetic or
geometric the assumption will be that the sequence is
either monotonic increasing or decreasing. So, for this
assignment, if the test data we use is a constant
sequence of numbers, the answers "arithmetic",
"geometric", "constant", or no classification will all
be acceptable.
23/03/06 Announcements on Assignment 1:
For assignment 1, everyone should note that we will
stick to conventional maths definition.
I.e. Quadratic progression can't have zero as the leading
coeffiecient (a can't be 0, otherwise it's not Quadratic).
Also for Geometric progression, r can not be 1. We will not
test your code on trivial cases such as when r = 1 for
geometric progression.
10/03/06 Mea culpa! In the offline transparencies I wrote today I
said that to show f(n) is O(g(n)) it suffices to show
lim f(n)/g(n) = 0. In fact it should be lim f(n)/g(n) = c
for some constant c (and 0 is one possibility). What is
true is that if c is 0 then f(n) is O(g(n)) but not the
the reverse. Thanks to the student who came up after the
lecture to ask about this. If anyone detects errors of
statements in lectures, please alert me quickly; I am
sometimes careless and will be grateful for corrections.
28/02/06 Students with timetable clashes and need a waiver, please
see me at the end of this Friday's lecture and I will sign
it once I check that the request is reasonable.
27/02/06 Welcome to COMP2011/2711 semester 1 2006. Professor
Norman Foo is your instructor. The tutors will be
named soon.
This is the last time that 2011/2711 are being offered.
New courses take their place from S2 on. 2711 students
share lectures with 2011, but are expected to master the
material to greater depth and possibly to do additional
parts of assignments. The 2711 final examination will be
slightly different from 2011.
