I have some opinion on the tutorial for 6.042. I find that every time in the tutorial, there are only one or two sheets of tutorial questions. We have a hard time to share and read the questions and it tskes us some time to read the question. Also, we do not know the problem of the other group so sometimes I find it difficult to catch what he is going to solve. So can you actually give each of us a separate sheet of the tutorial exercise so that we can be more clear about what's going on?

Alternatively, you might try putting the following at the end of the files you want to lock: % Keep these lines at the end of the file! % Local Variables: % eval: (require 'journal-lock) % eval: (if (buffer-file-name) (journal-lock-file (buffer-file-name))) % End: This provides a simple file-locking based on changing permissions, i.e., when you start editing a file, the permissions are changed so that only you have write permission. If someone else tries to edit the file, they'll get a warning that the file is already locked. When you finish editing and kill the buffer, the permissions revert to what they were before. I can't guarantee that it's immune to race conditions and it's prone to leaving the file locked if your emacs session ends abnormally (e.g., because of a system crash), but otherwise it seems to work pretty well.

Thanks. FYI: I found and corrected a typo in your link to H12. There's been lots of changes to the recitation list, so that's probably not current. I definitely have not modified it recently. At this point in the course, everyone better know where their tutorial and recitation assignments are. Yes, but we certainly need an accurate record of who belongs where, and I think it should be available to the students. I'd like one TA to be in charge of maintaining the class/recitation/tutorial list (online and offline). VOLUNTEER? In terms of grading, the TA's have tutorials on Wed (which run from 10-5), so there's really no block of time we're all free. I can grade the night of. In the past, we didn't have the graders help. If we have exactly 6 problems, then each of us can grade one (which generally takes 2-4 hours). I can almost certainly get the graders help, if you feel the need. -- Andrew Let's defer decision on this till after we have Q1 draft (tonight?). Meanwhile, everyone please indicate hours of availability for grading next wed. I'm free 10--5 that day.

We do not yet have the updated lists and other information which will enable you to send out the flags. The old freshmen evaluation forms have been replaced by a system of Fifth Week Flags for Freshman, where professors are required to give written feedback (preferably by email) to freshmen enrolled in their subjects who are performing at the D or F level. Each flag should request an immediate meeting with that student. These meetings should occur within a week to 10 days. I think you should feel free to send out flags to any freshmen whose performance could be improved, especially those on the low side of C, and to upperclass students who are in danger of failing. If you send a copy of the msg to me for Course VI students, I'll try to see that it gets to that students' advisor. Copies of the msg are to be sent to the students' advisors and the UAA (these email addresses will be provided). The Flags are supposed to be mailed right around the end of the fifth week, which is this Friday. The msgs should be brief and personal, reserving substantive points for the individual meetings. If you have any questions about this process, you may ask Peggy Enders or Bonnie Walters, x3-6771.

He attended the quiz, but didn't turn in his answers. He is in Parry/Jakov's section. He may or may not drop the course; he wants to continue. He is probably taking too many courses right now; he's not getting enough sleep and has a number of other difficulties (e.g. financial) to deal with, so life is not simple. Please be sensitive to his situation and try to give him a little extra assistance if necessary. I suggested that he might make better use of office hours. He does have a "tutor" for the course from the department, as of recently. I offered that we could "grade" his quiz if he turns it in. This would not be for the record (his quiz grade is officially 0) but for his own guidance in assessing how well he understands the material. If he does this, he might either turn in what he wrote down last night, or maybe work on it a bit more and then turn that in...

By definition of "having same cardinality" this is equivalent to showing there is a bijection between the two sets. This is possible to do, but it might be too hard. Therefore, we revised the problem to be as follows: Show there is a SURJECTION from [0,1) to [0,1) x [0,1).

Please send to me (achou@theory.lcs.mit.edu -- DO NOT send to 6042-teachers, 6042-tas, or 6042-forum) the times slots you have finals. Use the following format, (we will count final times electronically) For your finals, send me DATE-TIME DATE-TIME DATE-TIME where date is the day MON, TUE, WED, THU, FRI and time is AM or PM For example, if you send MON-PM WED-AM THU-PM I will interpret this message to mean you have 3 finals at the given times.

I was completely bewildered by question number four on the test, and, to be honest, I don't understand the solution, and will be going to my TA's office hours again this week. I don't claim to be one of the best students in the class, but it worries me that I can't make heads or tails of the solutions.

Is that the intended solution or it is a bug in the problem? --Daniele I can't make much sense of 2b and think we should cut it: What is the type of f? It can't be N-->N since there are NO strictly decreasing functions of this type. If it is N-->R+, such as f(n) = 1/(n+1), then f(O(n)) is ill-defined: for then f(n) = O(n), but (f(f(n)) is ill-typed since the range of f is not contained in the domain of f. If f:R+-->R+, then n = f(f(n)) is in f(O(n)) and is not bounded by f(0). Even wierder things happen in this case, and I don't think we want to study it. Instead, just use 2a, made a bit more interesting: Prove or disprove: 2^theta(n) = theta(2^n) Preface of prob 2 is awkwardly written. I suggest replacing it with repetition of the phrasing from tut7 prob 1: In class we defined $f = O(g)$ as a relation between functions $f\mbox{ and }g:\nats \to \nats$. We now define $O(g)$ to be the {\em set} of $f$ such that $f = O(g)$. Similarly for $\Theta(g)$. More generally, we define $h(O(g))$ to be the set of functions: \[ h(O(g)) ::= \{\,h(f(n)) \mid f(n) = O(g(n))\}. \] Similarly for $h(\Theta(g))$.

Reword as follows: List the following ten functions from left to right so that each function is "little-o" of the function to its right. PROB 3: reword first sentence: The general form of an inhomogeneous linear recurrence of degree 1 is: in part (b) change "x" to "f" PROB 6 The ideas all appear in the case d=2, and fixing d=2 makes evrything easier to read. Relabel part (d) be part (b)--it has nothing to do with current parts (b)(c). Relabel current (b) into (c). Insert a new part (d): Give explcit formulas for a_1 a_2 in terms of beta1 beta2. Finally, relabel current part (c) as (e), omitting its first sentence.

Reply-To: anneh@eecs.MIT.EDU I'm scheduling a meeting with all of the freshmen who've declared Course VI for Friday, April 17th, from 10 AM to 12 N. This is the day after classes end. Please ask your TAs or whoever will be scheduling final exam review sessions to avoid that time, as I need all the Course VI freshmen to be able to attend that meeting. I hope to assign advisors to just about all of them during that meeting. A review session scheduled then would really screw things up. Also, please remember that the end of the term is almost upon us, and decide when and how you want students to find out their final grades and see their finals. Freshmen are usually the most clueless on this matter, so be sure to pass out something in writing at least twice, and avoid the term "course secretary", which they're all sure means me!

Since you, and I have discussed this matter, I thought it might be helpful to have something to refresh my memory in late May. As we discussed this afternoon, , a grader in , came to me explaining that he had been referred by you to this office. was requesting a chance for make-up exam scheduled which was scheduled for this evening. His reason for wanting a make-up was that he had become unexpectedly overextended with problem sets to grade, primarily because the students had been having difficulties completing the work and several passed them in late. When I asked if he could get any help with the grading, he explained that he had mentioned this to the TAs but they were unable to give him any assistance before the deadline. After I discussed this matter with you, we agreed that it would be best for the student to take the exam. You expressed sympathy for the student and his need to complete his work responsibilities but felt that a make-up would open a "Pandora's Box". I agreed and confessed that the only argument that I could make in the student's behalf would be a "mercy plea". You stated that "mercy would be given when it was needed" - possibly at the end of the term when calculating grades. has told me that he will take the exam. Thank you for your concern about this student's welfare.

Her homework are almost ok: she got Homework: 58/70, 44/60, 46/50, 46/70, 17/70, 53/60, but she is performing very poorly at the quizes: Quiz1 29, Quiz2 26. She attended to all tutorials and her projected score is 55.1, ranking 18 from the bottom. She is a freshman and is taking the class pass/fail. I have already talked with her and worked with her during my office hours. It seems her problem at the quizes has been the time. She is not very confident in her understanding of the material, and she told me that doing the homeworks satisfactorily takes her a lot of time. She does not collaborate with other students for the homeworks. I think she is already working hard, and what she really needs is some more time to think about the material covered in the course. I don't think she should drop the class, even if she is probably going to get a bad grade also in the third quiz, but without knowing how decisions about pass/fail will be taken I couldn't give her advices about dropping the class, and I suggested her to get in touch with you. Another student in a similar situation that asked me about dropping the class is Rikert Thomas. Homeworks are ok, but he got 36 and 43 at the quizes.

He has only been to 3 tutorials, and has not turned in any of the homeworks (only ps7 which is not graded yet). His perfomance on the quizes is around 50%. I told him if he did better on the remaining quiz and the final, and did well on the problem sets he would probably pass, but that I wanted to check with the Professors in the course before giving a definite answer. I also asked him if there were any special circumstances we should consider, but there weren't any. My questions are: (1) Do we mind passing someone who practically blew off first two thirds of the course (no tutorials/no problem sets), but did OK on the tests? (2) Do we mind giving a C to such a student, provided he aces the rest of the tests?

Specifically, I propose that we hand out their "Notes 19" (Handout 49) to "Notes 26" (Handout 63). Notes 19-23 can be handed out immediately, and the remainder can wait a little bit. These should be reformatted, of course, to be consistent with our handout numberings, but should indicate that Karger/Leighton are the authors. Can someone take care of this, so that we get the 19-23 handout ready for Tuesday?
