Source Codes for HW1&2

Some students asked me to publish source codes for the homework. Here are those of HW1&2. Use them for reference.

HW1 Problem Set

HW2 Problem Set

HW1 Solution Manual

HW2 Solution Manual

Return HW1&2

I marked all your HW1&2 answer sheets and put them in the mail box in front of my office, room 426. Please come to take them.

Sorry for my great delay.

In HW1&2, 10 students got A, 14 students got B, and 16 students got C.

I awarded Tsukahara and Ino A+, since they showed excellence especially in solving optimization problem, some optional problems, and made few mistakes.

Anyone has a question about the rate come to my office.

Kohei

Correction for Solution Manual to HW1

I found an error in the solution manual to HW1(a)(i). There, I argued that A is not closed since it is open, but it is an insufficient argument. That we can take a convergent sequence to b which is not in A is the reason that it is not closed.

I might have made some other such mistakes...

Correction for Solution Manual to HW2

As is mentioned in the last TA session, I made some mistake in solving HW2 5(a)(iii).

I uploaded the revised version in the course web site, so please refer to it.

Thanks Igarashi for letting me know.

Kohei

Correction for HW3

Found the following typos in HW3.

Problem 4: "... if X is finite ..." should be replaced to "... if |X| is finite ...",
where |X| represents a cardinality of X.

Thanks to Kobayashi and Kubota for pointing it out.

HW1&2: Solution Manual

We have uploaded solution manual to HW1&2.
Please download and check it.

Kohei

Next TA Session: HW1 & 2

We hold a TA session tomorrow 4/24:8:30-10:10 at room 3.
We soon upload the solution manual to the homework, so please bring it to the session.

I must apologize that I cannot return HW tomorrow because I have a full schedule.
I will return the HW at next Wednesday. Sorry for the delay.
