All notes and assignments wil be posted on this website.
Submission of assignments and course project deliverables is via canvas.
This course covers a range of topics in programming languages, including lambda calculus and type theory, functional programming, logics for encoding programs, and automated verification techniques.
The goal is to expose students to a range of mathematical and practical tools for reasoning about programs.
The following will be populated as the course progresses:
-
Tue Welcome to the course / Intro to the beautiful lambda calculus
- notes
- Ch. 5 of TAPL

- notes
- Chs. 5 and 6 of TAPL
you might also find helpful the notes from Sampson's Cornell class—this and this

Assignments will be posted here:
| Assignment | Due date |
|---|---|
| asn1 | Feb 15 |
| asn2 | |
| asn3 | Mar 22 |
| asn4 | Apr 17 |

Performance will be evaluated as follows:
| Task | X% |
|---|---|
| Research project | 45% |
| Assignments (5) | 40% |
| Project presentation | 10% |
| Class participation | 5% |
For the final project, you can work on a problem of your choice with a partner or by yourself.
-
Deliverable 1 (Feb 5) Send me a list of three project ideas.
-
5%: Deliverable 2 (Feb 26) Submit a 2-3 page proposal including the following: The statement of the problem to be investigated An explanation of why the problem is interesting A description of what you propose to do. Explain the elements that you will have to build. Explain the elements that you can pick up from open-source sites. Explain the experiment(s) or performance measurement(s) that you plan to carry out. Two good approaches are State the hypothesis that you hope to refute. Complete the following sentence: "The experiments were designed to shed light on the following questions: . . ." Then explain what you plan to measure; how you will measure it (if it is not obvious); and where you will obtain test cases. List the tasks, broken down into two or three milestones
-
5%: Deliverable 3 (Apr 12) Submit a description of progress, implementation plan with completed steps checked off, and experimentation plan. Please turn in an updated proposal (with changes marked with changebars, and your new material added as "Appendix B: Progress Report".
-
10%: Deliverable 4 (last 2 weeks of class) 10-minute oral presentations (plus 5 minutes for questions/discussion) will be given during class. You will need to e-mail me an abstract (in plaintext) giving the title, project participants, and a two-paragraph to three-paragraph summary of what will be presented.
-
35%: Deliverable 5 (May 11) Final writeup: The final writeup should be modeled after a typical conference paper. There is no length requirement or limit, but I would expect it to be somewhere around 6-10 pages of ACM's double-column conference formats.
There are no required textbooks for this class. The following is a list of books that should be useful references for different parts of the course.
This is an excellent reference for our lambda calculus and types material
- [TAPL] Pierce, Types and Programming Languages. The MIT Press, 2002.
This is a free and excellent book that covers most material we cover in 704
- [FRAP] Chlipala Formal Reasoning About Programs
This book talks about decision procedures and their applications in verification.
- [CofC] Bradley and Manna, The Calculus of Computation. Spring, 2007.
This is a short book on operational, axiomatic, and denotational semantics.
- [Sem] Nielson and Nielson Semantics with Applications. Springer, 2007.
The following book covers data-flow analysis and abstract interpretation.
- [PA] Nielson et al., Principles of Program Analysis Springer, 1999.
This is another abstract interpretation resource.
- [AI] Abramsky and Hankin, An Introduction to Abstract Interpretation.
There are multiple courses at other universities that overlap with the material we cover in CS704. Here are some that I found helpful:
