Entry #10

The last week of lectures are coming up. I just started assignment 3 with my group on the weekend and so far I've understood a bit of it. The only reason I was understanding a bit of it was because in the past few weeks in the lectures I've been sleeping half the time.

The tutorials were a big help for me because I had understood the basics of Big Oh and Big Omega but haven't practiced much problems on it yet. So for question 1 and 2 on the assignment wasn't that hard because of the tutorials. But for the quiz, the placement of the 1/100 confused for for a while, was it part of the f? or was it part of the entire thing? Hopefully I got it right.

Note: HALTS are very confusing @-@

Entry #9

This week in our lectures, Prof. Heap showed us proof of Big Oh with limits and introduced us to limits. I didn't quite understand how the proof of the Big Oh with limits worked but after taking a quick glance in the next assignment I noticed we have to do some questions with this. I had just finished a 3 week long barrage of term tests and essays from my other 3 courses so I guess the stress from that is making me not understand this. Prof. Heap also showed us some interesting proofs of Big Oh.

In tutorials, our T.A. showed us how to do the first Big Oh proof with a different way of getting the c and b values different from what Prof. Heap showed us. I found this way of proof interesting but I found Prof. Heap's way of doing it easier for me than what my T.A. showed me.

Entry #8

I did the second term test the other day and I was disappointed at myself when doing it. I understood the first and second question on the test because they were questions of the assignment. But for some reason I blanked out and was confused on what to write on some of the parts of the proof. Hopefully I didn't do bad on the term test.
In the lectures we did some proofs with Big Oh's and I was confused with one of the proofs that Prof. Heap showed us. He had made c = 9/2 and b = 0 in one of the proofs and for the longest time I was trying to figure out why c = 9/2. Maybe I'll ask my T.A. during the next tutorial about this.

Entry #7

The assignment is finally done and the second term test is coming up. While working the assignment I found the proofs to be very challenging. I wasn't 100% sure of what to write for my proofs and sometimes was doubting my partner's answers because I thought your supposed to prove it like "blah". Like in question 3 of the assignment, the statement is false but I had thought it was true because I picked n = 5. So I got the results of 25 mod 11 = 3 and 5 mod 11 = 5. It looked right to me but my partner had to explain it to me thoroughly and used an example of 289 mod 11 = 3 and 17 mod 11 =/= 5 for me to finally get it.

Entry #6

I just started working on the assignment with my partners. So far determining if the statement is True or False and the steps to prove some of the questions wasn't that hard. But the structure of some questions is kind of confusing me. For example, is it supposed to be

Case 1: Assume ...
...
...

or

Case1: Assume ...
     ...
     ...

Tutorial really helped me understand some of the stuff we're doing for this assignment because I was way to sleep during class to pay attention.
