Grading Statistics
Hi all!
We have compiled statistics for the quizzes and homeworks so far. Keep in mind that the statistics that involve the pirates assignment are not complete, as we are not done grading it yet.

Graph assignment and grading
We hope you enjoyed the graph assignment (aka Pirates). The feedback we have from you is that it was generally viewed as a worthy assignment, but that it was hard, especially for the time allotted. We want to acknowledge this, and we will grade the assignment accordingly! Additionally, several of you have asked for "how am I doing?" feedback. We are developing some information that can help you judge your overall progress, and we expect to get this to you right after Thanksgiving. We don't want you to panic unnecessarily in preparing for the final, but rather, in fact, to enjoy the experience!! -- Chris and Bill (and the TAs also)

Creating groups for chess
Please be aware that when you invite a partner to join a chess group, you may see a FrontDesk server error. However, FrontDesk is still sending email invitations correctly, so you may safely ignore this error.
Thursday, November 12, 2009
One more (hopefully last) clarification
First: Your greedy bot will most likely not need/use a cartographer (if done correctly). This is okay and even expected.
Second: Don't just assume that one bot(MST-TSP or Greedy) should beat the other. Actually think about which one is better for TP and why. Again, for theory question 1, note that we are telling you whatever relative behavior between MST-TSP and Greedy that you see in TP will be identical to the relative outcome in TP Redux. This statement accounts for "tricky optimizations" that you might make.
--Adam
Greedy Bot
Just in case (I'd rather make sure I've said it, then have people not know), I wanted to make sure that everyone realizes that writing the GreedyCaptainBot IS a required part of the assignment. As stated in the documentation, it is tested in a private test. To make sure you are passing, you can run the MST-TSP-APPROX bot against your greedy bot (as this is exactly what we are doing!).
One more note: there is nothing wrong with using a greedy cartographer in addition to your greedy captain.
Hope that helps,
Adam

MST-TSP-TOUR Clarifications/Hint
Sorry for the delay in getting these up! There seems to be a lot of confusion in how to do MST-TSP-TOUR, so I wanted to officially make a few clarifications.
(1) The graph you recieve will not necessarily be complete. This is the point of "completing the graph." To "complete the graph" your edges in the graph should be minimal path weights. This is convieniently where Dijkstra comes in.
(2) To deal with a subset of vertices, you should just make a complete graph ON THOSE VERTICES, before creating an MST ON THOSE VERTICES.
(3) The vertices in the list that you return represent a list of destinations. Imagine that you are at the vertex you want to start from. The list of vertices tells you where to go next. So, as a result of this, the first vertex in the list is NOT the goal, but the last is.
Hope that helps!

Daegun's office hour today (11/10) is canceled
I am afraid I need to cancel today's office hour. I will be available via e-mail if you need any immediate help. Sorry for the short notice guys!
Dynprog targeted regrade
There was a mistake in the dynprog rubric for 1 (d), consequently, stating that some rooms e_i at times t_j were inaccessible if "n+1-i > T-1-j" for the n and T given in the problem intro (or an equivalent condition) was sometimes marked off a point, even though it is accurate. If you experienced this specific error in grading, then turn back in your graded dynprog homework to your TA next recitation (November 11th) and this specific error will be corrected.
If for some reason your homework is not resubmitted that recitation, you can get into contact with Trevor Burns (tpburns@andrew.cmu.edu) to work it out, preferably by going to his office hours (Mondays 7-8pm GHC 4122) with the homework in hand. For any other grading concerns you should pursue the normal avenues of recourse. Thanks for your patience.

Oops...(pertaining to graphs again)
Apparently, the staff Kruskal was using the student UF...my bad. It's fixed now. You may want to re-submit to FrontDesk...
Sorry for the inconvenience.

Graphs Lab Changes (again)
I have made a few changes that shouldn't affect most people, but I'm letting you know about them anyway. (1) The compareTo code for WeightedEdge has been changed to actually take the weight into account. (2) The staff tests have been fixed to rely less on the graphs you guys make, and now use the staff graph to test your algorithms. (3) The staff code now takes self-loops into account; you will not be penalized if you do not.

Chanwoo's office hour moved once again.
Hi, I will cancel my office this week and instead I will have my office hour for two hours (4 PM to 6 PM) in the next week.
This is a onetime change due to a on-going project in our group. I'm sorry about this inconvenience.
Midterm Grades Released
The mean and median for the exam were both 50 points out of 71. You can pick up your exam outside Dr. Scherlis' office between 8am and 3pm. TAs will also bring your exams to recitation next week.

Good News Everyone!
Hi all,
We have decided to move the due date of Traveling Pirates forward two days. A few notes about this:
1) This is NOT a reason to delay starting the assignment; in fact, the reason we are extending the time you have for the lab is that it is non-trivial.
2) This has nothing to do with FrontDesk downtime; if it does occur, we will take this into consideration (and possibly move it forward further). Do not count on FrontDesk dying though.
3) The release date of Chess will NOT be moved forward; that is, you will simultaneously have two labs out for a few days.
Good luck on the exam tomorrow!!!!!

Compression
Due to hardware issues, we have decided to give an additional extension for those who want to use late days. If your last handin was Sunday 10/18 11:59PM or earlier, you have used 0 late days. If your last handin was Monday 10/19 11:59PM or earlier, you have used 1 late day. If your last handin is Wednesday 10/21 11:59 *AM* or earlier, you have used 2 late days. That is, you have a 12-hour extension, if you want to use 2 late days on Compression.
Friday, October 16, 2009
FrontDesk back up + 1 day extension
FrontDesk is back up. Please check your most recent assignment submission; if it was not graded, you will need to resubmit your assignment.
Because of the problems with FrontDesk, we have granted a 1 day extension. The new due date is 10/18 11:59 PM; if you use 2 late days, the final deadline is 10/20 11:59 PM.

I'm moving my office hours this week to Monday 10/12, 4:30pm-5:30pm, GHC 4122. Sorry for all the schedule changes I've made this semester; there should be more consistency in the 2nd half of the semester.

Compression lab is now due 10/17
The due date for Compression has been moved from 10/15 11:59 PM to 10/17 11:59 PM. This also means that you may turn in the assignment by 10/18 11:59 PM at the cost of 1 late day, and by 10/19 11:59 PM at the cost of 2 late days.
Also, in preparation for the lab, I recommend the following PDF, prepared by Owen Durni, that shows all of the compressions and transformations that you will be implementing. Note also that you will be implementing the Burrows-Wheeler transformation slightly differently than what was presented in recitation.

Please Include Link to Frontdesk Submission in DBoard Posts
If you have a question about a specific error or case that you are seeing on Frontdesk, please include a link to your submission so the course staff can quickly find your submission. At the very least, post your andrew id as that is the index the staff has for searching for submission.
Watching 211 videos
Here is how to watch: Click on the "Lectures" link on the left. Click on a video. You may be asked to authenticate with your andrew password.
- Principal uses of the video are: (1) using lecture content to find answers to specific technical questions, (2) get clarification on some part of the lecture that may have been confusing the first time around, and (3) review later in the semester. Videos are less effective as a lecture substitute -- better to attend the live event.
- Some how-to info: (1) Use the slide tray on the bottom to navigate -- just click on a slide or image. (2) Click on the "powerpoint" tab above the main window to see the powerpoint slides rather than the video of the screen or the screen capture (when we do this). Select the "+" on upper right to expand the image. (3) Videos that show powerpoint directly have a search function on lower left that you can use to find specific material -- the index is built from text on the slides. (4) Try also the note-taking tab -- you can create your own private notes or a public channel.
- If you can't get authenticated, read this: This system uses CMU's "active directory" (ANDREW.AD.CMU.EDU) domain and it has one glitch: If your authentication fails, go to myandrew and reset your password to itself. (Why this works I cannot explain.)
Thursday, September 03, 2009

Both endgame evaluators are now extra credit
It has been brought to our attention that there was a misprint in the starter code of the TestedEvaluator, which incorrectly labeled the EndgameEvaluator as extra credit. Because of this, both parts of the EndgameEvaluator (endgameEvaluatorTest0 and endgameEvaluatorExtraCreditTest) are now extra credit. The assignment docs will NOT be updated to reflect this due to Frontdesk limitations. I personally apologize for the misprint.
My office hour today(4/28) is moved
I'm moving my office hour today to 2:00-3:00 on this Thursday instead of the usual time. It will be still in the west wing cluster. Sorry for the inconvenience.

note sheet for midterm exam
Our midterm exam will be closed-book, closed-notes, etc, except: you may bring a single 8 1/2 by 11 sheet of paper, filled front and back with any notes you want. During the exam you must use only your own note sheet, and you will turn in your notes with your midterm exam.
We encourage you to make your own note sheet without collaborating with your classmates. We've found that the process of making your own notes will greatly help you study for the exam.
midterm review session Sunday night
We will have a review session Sunday night, from 8 - 10 pm, in Wean Hall 7500. Please come with questions: we will have no pre-prepared material.

cheating on early homeworks and quizzes
We've detected at least four cheating cases on the early homework assignments and quizzes, and we'll be handling those cases starting Tuesday night. If you think you have cheated or otherwise violated our collaboration policy, now is your chance to save yourself: your punishment will be much less harsh if you volunteer an unsolicited confession before we contact you. If you might have any reason to be concerned, please send an email to charlie@cs.cmu.edu immediately.

Expect FrontDesk slowness Thursday night
The FrontDesk developer warned us that FrontDesk is going to be extremely slow Thursday night, possibly requiring two or more hours to grade each submission.
To help yourself (and each other), please submit to FrontDesk as early and as rarely as possible. Try to avoid using FrontDesk as a testing server; it won't work on Thursday night. Instead, please write a good suite of local JUnit tests so that you only need to submit to FrontDesk when your code has passed all your local tests.

ExpressionTrees Theory Submission
Ideally you should submit your answers to the expression tree theory questions in the theory.txt (plain text) file to Frontdesk. Since it seems we have confused some students, we will also accept solutions in pdf, which you should include with your submission to Frontdesk in the src directory. On future assignments we will only accept hardcopies of typeset solutions (in recitation).

Link to Frontdesk when asking TAs about your code
When you have a specific question about your assignment and you want your TA to be able to see the code you've written so far, please link to the appropriate submission on Frontdesk (rather than attaching/including portions of your source).
The link will look something like this: https://fd.cs.cmu.edu/frontdesk/codeview/?sub=#####.

Lecture 04 written notes posted
By popular request I have posted the written notes from today's lecture. I will not post the written notes in the future. I am only posting today's notes because of the large number of written notes and fast pace of the lecture.
