Midterm Grades

Midterm grades are up, scores weren't all that bad.

Average: 65.8% Max: 95%

Tomorrow in recitation you will get your exams back and we will go over the questions. If you happen to put down the wrong section, there is a chance another TA will have your exam.

Here is a histogram: http://www.ece.cmu.edu/~xfu/grades.pdf

Lecture 14: Compression II

This lecture reviewed Huffman trees, discussed Kolmogorov-Chaitin complexity,
and described the Lempel-Ziv-Welch (LZW) algorithm. (PS)

Practice Midterms

Note that the material covered varies per semester, and so not all of the problems on these exams will be relevant. https://www.cs.cmu.edu/~211/content/midterm_f07.pdf https://www.cs.cmu.edu/~211/content/midterm_s07.pdf

Asymptotic Handout

Made an asymptotic handout last semester, it is at: http://www.ece.cmu.edu/~xfu/ Handout and answers are in there. Contains some sample problems on using masters theorem, solving recurrences. Explanations are quite thorough if you had trouble understanding some of it the first time.

Super Office Hour

UPDATE: Room = Wean 5419 cluster. We, the TAs, will be holding a very large "office hour" tomorrow, Sunday, from 3-4:30pm. There will be no formal review session for the exam. If you want us to go over material at the office hour, please come with specific problems or questions.

Office Hours Canceled #2

My office hours on Tuesday 3/4 will also be canceled in favor of grading the midterm. If anyone has questions, feel free to email me.
