Week 3

Week 3:

The main goals for Week 3 are to:

  • Show how simple models of computing can result in complex behavior.
  • Begin building a bridge from theoretical models of computing (like straightline programs and boolean circuits) to practical implementations of computing (like Python and integrated circuits).
  • Explore the powers and limitations of a model of computing, including being able to understand the details of how to use that model, and why it is defined in the way chosen.

Cohort Problems

These are the problems you should discuss in your Cohort Meeting, and everyone in your cohort should be prepared to present and discuss solutions to at the Assessed Cohort Meeting:

Cohort Problems for Week 3 [PDF]
Programming Problems for Week 3 [adders.py]

The problems are posted here and we think its a good idea to look at them early, but you’re not expected to be able to solve them until after doing the readings and watching the videos below.

After the Assessed Cohort Meeting, your Cohort Leader will select one problem that your cohort needs to write-up and submit. The write-up is due by 11:59pm on the day after your assessed cohort meeting (see the schedule above).

The PS3 Template provides directions and a template for producing the PDF file you will submit as your write-up.
