Students enrolled in this class are expected to check this web page regularly. Lecture notes and important other material will be posted here.
CS522 is an advanced course on semantics of programming languages. Various semantic approaches and related aspects will be defined and investigated. Executable semantics of various programming languages and paradigms will be discussed, together with major theoretical models.

Lecture Notes, Useful Material
The links below provide you with useful material for this class, including complete lecture notes. These materials will be added by need and more topics will be added.
- Conventional Semantic Approaches
| HW2 (due Wednesday, October 3 - easy HW, so earlier submission possible and appreciated)
| The following exercises related to denotational semantics are from the book material above: Exercises 80, 81, 82 ((page 168; write these up on paper, or in a PDF); Exercise 83 (page 169; do it only in Maude (that is, not on paper) by modifying the provided Maude code for HW2 ).
| HW3 (due Monday, October 15)
| Combine all the individual extensions of IMP in the provided Maude code for HW3 into the IMP++ language. Read the book material above for all the technical details. You should create a subfolder of imp called 6-imp++, and that should have four subfolders, one for each semantic style. Provide also three IMP++ programs.
| HW4 (due Monday, October 29)
| Same as HW3 but for the three additional semantic approaches discussed in the lecture notes above: MSOS, RSEC, and CHAM. Use this provided Maude code for HW4 . Handle also a short essay discussing the advantages and limitations of each of the semantic approaches discussed so far in class, assigning a (justified) score between 1 and 10 to each of them.
