Month: January 2017

It’s Friday the 13th, and we’re studying reductions!! (Boo.)

Right, um.. on to regular business.

We’ll continue working on the resident-hospital matching problem.

A few notes:

• Read Chapter 2 of the textbook for Monday. Most of this should be review! Sections 2.3 and 2.4 are especially valuable for applied review of asymptotic analysis. This is what you should be good at to be awesome computer scientists.
• Finish the pre-class quiz due Sunday at 10PM. You may find that you can answer most questions without having to read the chapter. Please do at least skim the chapter anyway!
• Work on your assignment! It’s due in a week (20 Jan at 10PM).
• Register for a tutorial if you haven’t already.
• Go to tutorial! Next week, the format is up to your TAs. They are thinking about reviewing critical topics and working on assignment and assignment-like problems.
• Here’s a sample solution to our reduction notes.

We’re continuing with stable marriage with an eye to reductions today. No new handouts, but an old one and plenty of notes:

• Pre-class quiz review: As of 3PM Sunday, this was going very well, with fictional clicker questions we’re supposedly asking in class causing the most trouble. (Well, and the soulless candy, but we said we’d give credit for that.) There are no clicker questions in class, and the worksheets aren’t graded… BUT CPSC 320 is a hard course, and the practice and mini-lectures you get in class will make a big difference to your success. So, please do attend!
• And now off to the handout on reductions and stable marriage.
• For next class, read section 1.2 (but no pre-class quiz yet). Be aware that the reading for Monday will be all of Chapter 2. That’s because much of Chapter 2 should be review. You may want to start early, however!
• Tutorial quizzes are posting as each tutorial finishes. Start solving them, since your assignment will be composed of the tutorial quizzes! Your assignment will be due 10PM on 20 Jan (Friday).

Today we’ll continue the first stable marriage handout and (maybe!) start talking about the critical concept of reductions on our next worksheet.

Important notes for today:

• Here’s our new handout on reductions and stable marriage.
• As of ~3PM (before the 10PM deadline), the pre-class quiz was going well. The vast majority of people (well over 80%) answered each of the three pre-class quiz questions correctly. Be sure to finish going through the worked example if you had trouble, and ask on Piazza if you’re still unsure about the quiz!
• For next class, review the syllabus.
• The next pre-class quiz is due by 10PM on 2017/01/10 (Tue) and is about the syllabus. We hope you’ll find this a lighter pre-class quiz :). It should already have been mailed to you.(There won’t be a pre-class quiz due Thursday. Yay!)
• Before your tutorial, read the quiz pre-readings. These are (vague, wordy) problem domains that would take too much time to read and understand during the quiz.
• The assignment version of the tutorial quiz questions will release shortly after each tutorial. Start looking those over and working on them!
