Midterm Study Guide

The midterm will cover the material through the first lecture of week 5 of the course—Prolog will not be included on the midterm.

You may be asked to write some small functions in Scheme—you will not lose points for minor syntactic errors.

You may bring a single, hand-written, two-sided, 8.5” x 11” sheet of notes to the exam. This sheet must have your name on it, and it will be collected with your exam.

No electronic devices may be used during the exam. Please ensure that all electronic devices are out of sight during the exam. This also implies that you may not listen to music on your phone during the exam.

I suggest you focus on the following topics:

  1. Lambda calculus. Do not worry about the evaluation rules—we will see those again in the second half of the course.

  2. Recursive functions in Scheme. Understand base and inductive/recursive cases.

  3. State. Understand set!.

  4. Streams. Understand how they are implemented using force and delay, and understand how to construct and use streams.

  5. Higher-order functions. Understand map, filter, and the various varieties of fold. How can folds be used to implement other functions?

  6. The environment model of evaluation. You should be able to explain how an expression will be evaluated without asking an interpreter to evaluate it for you.

  7. The metacircular interpreter.

  8. Lazy evaluation.

  9. Implementing search. Understand how the amb interpreter implements search.
