Current Assignments
12 May
Review or Turing machines: we have CC225 from 9:15 to 10:15 on Monday. We can talk philosophy or build machines or both if you like.

Test: Our final exam 10:30 -- 12:30 in class. Here are some themes:
  • Explain the Turing test (what is the test set-up? What is this strange set-up meant to control for?). (Some folks -- for shame! -- forgot this very important concept. Turing calls it the "imitation game," but it is not called the "Turing Test." We read about it here.)
  • Stating and understanding Godel's First Incompleteness Theorem;
  • Knowing how to give an informal intepretation of the Godel sentence;
  • Understanding Godel numbering;
  • Basic understanding of Turing machines;
  • the Halting Problem and either reductio showing the problem cannot be solved (that is, prove the Halting result using either the diagonal argument or the impossible machine argument);
  • Definition of Kolmogorov Complexity and Chaitin Random;
  • interpreting the import of the Halting Problem;
  • defining complexity (the definition of descriptive complexity);
  • the incompressibility result;
  • Making a simple Turing machine;
  • Prove |R| > |N| using Cantor's diagonal argument;
Also: I'm going to try to get us a room where we can have a Turing Machine workshop from 9:15 -- 10:15. That'll be a time where we can work together on any machine you want to work on.
14 May
We can work on Turing Machines from 1:30 to 2:30 p.m. in room CC232 if you like.
16 May
Last day to hand in a Turing Machine.
