The finals have been graded, and the grades are released. The average is 67.5. The median is 67. The standard deviation is 15. Below is a histogram for the exam.

Extra Office Hours for Last Minute Questions

I'll have some extra office hours tonight for last minute questions about the exam from 7-9 PM in WeH 3130.

Lecture in DH 2315 Today

Professor Sleator will talk about the Game of Life!

Office Hours Change

I have a project meeting this Thursday afternoon and can not be at my regular office hour. I am changing my office hour for this week to Tuesday from 7pm to 9pm. Sorry for any inconvenience. Joy

Office Hours Change

I have to work on a group project tomorrow afternoon, so I'm going to have to leave my office hours around 2:00PM instead of 3:30PM. Sorry for any inconvenience.

Graph Assignment Average

The average on the graph assignment so far is an 83.75

Final Exam Review Session

We'll have a final exam review session on Sunday, May 6 from 3-5 pm in WeH 7500. Practice exams are posted below. Please come with specific questions from previous exams or material as trying to cram 30 lectures into 2 hours is impossible.

Old Final Exams

I posted some old final exams under Documents. This includes the last two 211 finals, which should be very similar to this semester's. I've also posted a zip of some really old finals for further practice problems. Where we had them, I posted the solutions. Remember the final is Tuesday, May 8.

Lectures in DH 2315

Lectures for both sections will be in DH 2315 this week. I'll be covering parallel algorithms.

My Office Hours

I did not hold office hours the past Monday due to my 36-226 midterm held in the evening. However, I forgot to make an announcement to that effect before the date. My sincerest apologies for any inconvenience caused to anyone due to my oversight.

Averages so far

We've been behind on posting averages, and I forgot what we've posted, so here it is: quiz1: 78.97 quiz2: 66.46 quiz3: 87.58 quiz4: 88.32 expr-tree: 89.45 snake: 83.89 dp-part-a: 17.75 dp-everything-else: 65.29 compression: 81.02 midterm: 70.91 These averages are computed with the people who were in the class at the time, so they might be a bit inflated after people drop. There weren't enough graph assignments graded yet [including my own section :-) ] to merit posting an average, but I'll post one soon. If I forget and it's been a while, shoot me an email. Hope everyone has a fun Carnival!

Chess Assignment Released

In case you have not noticed, the chess assignment has been released. It is due May 5 at 11:59 pm, the last day of classes. Be aware, you cannot use late days for this assignment. As this assignment is open ended and there is room for extra credit, start early and have fun with it!

Tuesday's lecture in DH 2315

Reminder: Lecture for both sections on Tuesday, April 16, will be DH 2315.

Office Hours Moved

I have to move my office hours tomorrow, so they will now be 7:30-9pm, instead of 4:30-6pm. They will still be in Wean 3130. Sorry for any inconvenience.

Graph Assignment Released

The graph assignment is now available on FrontDesk. It is due April 12 at 11:59PM, so you have two weeks to complete it. As many of you noticed last night, the job queue on FrontDesk can get quite long right before the deadline when a lot of people are submitting. Start early and this won't be a problem.

Burrows-Wheeler Transform Header

We did not fully specify the Burrows-Wheeler Header format in the assignment writeup, so please follow this addendum: Your header must be the first four bytes of the transformed files. It stores the start index value from highest order byte to lowest order byte. The provided example files reflect this header format for comparison purposes. Sorry for any confusion this caused.

Stuck in Chicago

To cut a long story short, I won't be back in Pittsburgh until late Monday night, and I need to cancel my office hours. If you have any pressing concerns, please try to contact another TA as I will not have internet access until I get back to school. Thank you
