We found some notes that are close to solutions for Winter 2003's exam. See the "Assignments, Quizzes and Exams" page.
The marks are posted. The assignments can be picked-up from outside Gary's office.
See the Marks page. The assignments will be dropped off to the CSSU tomorrow.
The solutions have some numbering problems, but you probably figured that out. Also, the conclusions in 6(a) should have (n+3)^2 inbetween c_1 n^2 and c_2 n^2, not n^2. We've updated the files, but if you printed an old version it's not worth reprinting just for this.
The solutions don't count "." and "[]" as steps, but it's okay if you did. The markers will allow either approach.

This message is for students in Jen's L0301 section.
In class today, we discussed the F03 Quiz 5 question:
The formula 1/(1-x) - 1/(1+x) (when x != +1 and x != -1) is unstable and we were looking
for a stable alternative. We weren't able to find one, and
that is because there isn't actually a stable way to do this computation.
The formula above is unstable due to the potential for catastrophic cancellation when x is close to +/- 1, or when x is close to 0 (making 1/(1-x) close to 1/(1+x)).
The quiz question actually asked for a more stable alternative. A more stable alternative is to find the common denominator and combine these two fractions to get: 2x/(1-x^2). That removes the instabilty when x is close to 0. There is still the potential for catastophic cancellation when x is close to +/- 1
For the next two weeks, my office hours will be:
The First-year Academic Offence Coordinator is investigating several suspected plagiarism cases on Assignments 3 and 4.
Please complete Assignment 5 entirely on your own, without the aid of your classmates. If you have questions about the assignment ask your instructor or attend the TA help sessions.
For the students in Jen's sections, we counted the running time steps slightly differently than Gary's sections (and different from the notes that are posted). We will accept either convention (as long as you pick one of the conventions and use it consistently).
The solution to this quiz has been corrected and reposted.

Subject: IMPORTANT changes to CSC program admission requirements for 2004/05
Below are two important changes to the admission requirements for CSC Subject POSts. They will take effect beginning in the next admission cycle coming up in June 2004.
Please read this carefully, and if you have any questions you can
- contact the undergrad office
- or attend an upcoming Info Session on CSC Admissions
Wed 31 Mar, 5-6 pm, BA 1190
Note that these changes provide more ways to gain admission to our programs.
CSC165H/240H accepted
=======================================
Summary: You can use your CSC165H/240H grade in place of your MAT137Y grade
for program admission.
For the purposes of program admission, a grade of 65% in CSC165H will be accepted as an alternative to a 60% in the appropriate calculus course. Calculus continues to be required for program completion, and the normal time to take the course continues to be first year.
The details
-----------
For all programs except Human-Computer Interaction:
old requirement: 60% in MAT137Y/MAT157Y.
new requirement: either 60% in MAT137Y/MAT157Y
or 65% in CSC165H/CSC240H
For Human-Computer Interaction:
old requirement: 60% in MAT135Y/137Y/MAT157Y
new requirement: either 60% in MAT135Y/137Y/MAT157Y
or 65% in CSC165H/CSC240H
The other admission requirements, such as 65% in CSC148H/CSC150H, remain unchanged.
Retakes
========================================
Summary: You no longer need to earn 10% higher on retaking a required
course for program admission.
The admission requirements for the major and specialist programs are being harmonized. As a result, the CGPA cutoff for both programs will be the same. For 2004/05, that cutoff will be 2.0.
Students who must repeat a required course in order to achieve the required grade used to be expected to earn 10% higher on the retake (e.g., 75% in CSC148H). If they met only the original requirement on the retake (e.g., earned at least 65% but not 75% in CSC148H), they were admitted to the major only. See http://www.cs.utoronto.ca/DCS/Undergrad/advice/ programAdmissionAlternatives.html#requiredLow for details (remove the linebreak before following this link). As part of the harmonization of the major and specialist, the requirement to earn 10% higher on retake will be removed.
Students who must repeat a required course for program admission
should watch out for these requirements:
- If you need to repeat CSC148H, you must not take more than
two CSC half-courses at the 200 level or above before
repeating CSC148H.
- If you need to repeat CSC165H/240H, you must not take more than
two CSC half-courses at the 200 level or above before
repeating CSC165H/240H.
- If you need to repeat MAT137Y, you must not take a second-year
calculus or analysis course before repeating MAT137Y.
- You will not be admitted if you have more than four grades
below 60 in CSC courses at the 200-level or above.
These are not new rules (except that there is now an option to repeat
CSC165H/240H, if necessary). The last rule has been relaxed slightly, as
part of harmonizing admission requirements for the major and specialist.

On the assignment handout, question 7(c) says "Do part (a) again...". It should say "Do part (b) again...".
Also, instead of O1, it should say O2.
They've been posted in the usual place. We've changed the way the pdf file is produced, since it was causing problems for one of the students. Let me (Gary) know if the new approach causes you any problems.
For A4 Q1, a completely formal proof is not necessary. You should follow the guidelines that we provided for A3 (see Level of detail in A3).
Question 7 states "We've been examining functions from N to R+". It should say, "We've been examining functions from N to R>=0"
Since A2 and A3 had their due dates extended, we've extended the due date for A4. Both A4 and it's due date are on the assignments page.
The schedule for TA Office Hours has changed, so that some of the sessions are held in the evening. Please see the schedule on the Contact Information page.
They are posted on the assignments page.
Some students have asked how formal and detailed they should be in their proofs. A simple guide: as detailed as the statements given. In questions 1 and 2, the statements contain all the details, so you should give completely formal proofs. But in questions 3 and 4, the statements refer to the details of f3 and f4, whose effects aren't given in the statements themselves, so when you get to the point in your proofs where you talk about them you can be less formal.
See the Current Marks page.
Jen Campbell is holding an extra office hour from 1pm-2pm on Friday, March 5.
Available in the usual place.
The cs website was down over the weekend, so some students couldn't get A3 to work on. We're extending the due date to Monday March 8th at 6pm so everyone gets a weekend for it. (We've made the time 6pm instead of 4pm, since many evening students come in for 6pm tutorial). The late penalties apply for next Tuesday instead of this Friday.
The marks for Assignment 1, Quiz 1 and Assignment 2 are now available on the "Current Marks" page.

If you did not pick up your assignment 1 in tutorial or lecture, then Jen Campbell has it. You can pick it up from her during office hours.
It's on the "Assignments, Quizzes and Exams" page.
Content: Any of the material covered in lectures, tutorials, quizzes and assignments may be tested on the midterm.
Time and location: The midterm will be held on Monday, February 23, 2004. L0101, L0201, and L0301 students will write the midterm during lecture in BA 1160. L5101 students will write the midterm at 6pm in BA 1160.
Past midterms: The midterms from the Winter and Fall 2003 have been posted on the "Assignments, Quizzes and Exams" page.
No, you cannot use switch statements in this question.
In A2, question 1(b), we provide you will a Java method. We want you to re-write this Java method without using "if", "? :" and "while" loops. Your answer to this question should be Java code (not English and not precise symbolic notation).
Question 1 on A2 states not to use the variant "? :".
"? :" is like an if-else that returns a value. For example,
if (x > y)
m = x;
else
m = y;
can be written in one line as
m = (x > y) ? x : y;
In general "(cond) ? expr1 : expr2" returns expr1 if cond is true and expr2 otherwise.
